The Germans did, it was called the 109, which fortunately for them was just manoeuvrable enough to be competitive when often forced into that situation.
I'm not sure I would say that, it seemed more maneuverable than the P-51 at lower speeds, similar to the P-40 at some speeds.
The US did too later, with things like the F-105, F-104 and so on, all rather less than successful....
The F-105 had to do more with the fact that the US didn't have an attack category, or more accurately some kind of small light-bomber category that was suitably to meet the tactical needs. As a result fighters filled the roles up and, to make it worse, the nuclear delivery role mattered more than agility.
As for the F-104, that is a more valid complaint: If I recall it was an example of...
- The United States and most European air arms valued speed, maybe speed and climb rate first, then roll rate and agility second: It had to do with the ability to have the initiative, the ability to disengage at will first, and then be able to mix it up second. This is not so say maneuverability isn't important, but a person tasked with relentless prioritization might end up arriving at this if forced to choose.
- The F-104 was initially designed to fly faster, climb faster and higher than any enemy fighter, but maneuverability was likely assumed to be an important variable -- it's sad that sometimes you have to explicitly say things that should be implicit, but it was more complicated than that.
- The USAF was initially pretty accommodating of this because there was a war on, and the pilots on the front lines clearly knew best
- The USAF wanted the aircraft also to be able to sustain Mach 2 performance either out of the speed requirement and/or the desire to use it as some form of day-interceptor, which ensured speed would remain an issue
- The Mach 2 requirements seemed to ensure that it would be prioritized above other things such as maneuverability, which would have resulted in things like enlarged wings.
- It could fly very high... the problem is that it couldn't fly as high as desired while retaining any real maneuverability subsonic.
Interestingly the British requirements that led to the Spitfire and Hurricane also had little about manoeuvrability.
The Hurricane was originally intended to be a fighter and later converted into an interceptor design with 8 x 0.303's. I'm not sure if the Spitfire was totally designed for interception off the bat, but the eight 303's came later, and that in turn actually played a role in leading to the elliptical wing (a decent airfoil that could stuff all eight guns in), also the company had an interest in the idea before. As for little being said about agility, I'm not sure if I would say that even about the spitfire: There was a stipulation for 6g with an overload of 9g (1.5).
So the 109 was good enough in most flight regimes to be (and stay) competitive. For example, against a Mustang, below 250-275mph it would hold its own (at least), above that the Mustang had the advantage in terms of turning (and definitely rolling). If they had just fixed up those rubbish elevators and ailerons it would have been even more dangerous that it was.
I'm confused here... are we talking about the P-51 or Me-109?
But the same (absolutely brilliant) work meant that a Spit would have good elevator authority even at very high speeds.
So the configuration of the thin fuselage, the tail based on the size of the wings, and the wings based on the massive fillets, played a role in the Spitfire's high dive-mach?
Everyone says that the Mustang was a superior aerodynamic design, personally I disagree totally . . . . then it's mach limit, then it's stall issues then
When you're talking about stall characteristics you mean issues with the tendency to spin? As for the mach limit, from what I remember Mach 0.75 was considered decent for the time, and it could be pushed up to 0.80-0.84 without coming unglued. Compared to the Spitfire, sure it was inferior, but almost everybody was.
Superb radiator design and superb frontal design (thanks to an 'unqualified air racer', NA's genius was to use him properly) and far (far) better quality control.
Unqualified air-racer?

What's with him and his desire to distort or fudge information?
That 5G limit may be expanded at a later date - I think comparing this to Shermans or F-4s lack of cannons is a bit far reaching however as we do know history has a way of repeating itself.
While I'm not an aerospace engineer, I do remember it being said by people who served in the US Navy, and some people who did seem to have some engineering expertise, that it was best to build strength into a design off the bat, rather than attempt to add it in later.
