French have literally nothing to offer in terms of support to the AMCA program and neither will their help speed up its development.
Apart from some imported LRUs which will become a pain in the *censored* if the supply chain are effed up again, there is literally zero that they can give the program which we don't have already.
FCAS was an audacious science project that is nearing its end thanks to age old partnership arguments between France, Germany and Spain.
It's collapse is not a question of if, but when.
If the Govt and the IAF are dead serious about AMCA, then they need to fund it to the magnitude of the deal sizes of P75I and MRFA.
