I don't believe those were endlessly dangled, but were sent soon after they were proposed. There are three categories it seems of military aid to Ukraine: there's those that are proposed but will not be sent ever or until the war's over, likely the F-16; those that are proposed, denied and then eventually sent, like the Leopard 2 tanks (or perhaps your AMX10s); and third, those that spare the endless chatter and after a short preparatory phase just get sent, such as the thousands of MANPADS and MANPATS sent from Feb 2022 onwards.
Air power seems to be a line NATO is reticent to cross. After eleven months of fighting the only western-designed manned aircraft sent to Ukraine are a trio of retired, and stripped out former FAA Westland Sea Kings. I wonder what will be the next manned aircraft to Ukraine from the west. The Mirage would be good, but I think it's more likely going next be another rotary, maybe old UH-1 Iroquois or Twin Hueys. Ukraine's best chance for additional fighters for now is for their backers to scrape up more MiG-29s from the globe.
