Most A-10 CAS is now delivered from middle altitude via PGM.
The F-35 will certainly be at least as good at that than the A-10.
The whole concept of recent CAS operations is to avoid that whole ground-fire issue by remaining out of range - and that includes A-10s.
Sorry to burst your WW2-era mindset, glad rag, but getting into "read the nametag on his uniform before you shoot him with your pistol" is no longer a viable CAS method.
