Almost certainly it is just spin from Biden's puppet masters.
Already planned 495th FS & 493rd FS. There aren't the facilities at RAF Lakenheath for 6 x sqns & I don't see the F-15E being withdrawn from 492nd FS & 494th FS until the F-35A can carry the full range of weapons.
This from US SecDef appears to clarify 2 x F-35A sqns total forward in Europe.
