It is not that I mean to be a ****, but that I can't help to not notice flaws.
While everyone's going nuts about the modifier kits, I took a look at the alphas kits. And they need revision, to ensure they properly fulfill their "cadet-y" qualities with the proper Math symbols present.
I'll exemplify this with the BEFR kit, which should make its point clearly enough:
None of the five letters (A, Q, W, Z, M) has its corresponding math symbol adjusted. Granted, "French Cadet" keyboards did not exist, but that begs the question of whether to move the letters but not the Math symbols, or to move them both (and of course it has to be the former, not the latter), but the kits as stand now would leave those letters unaccompanied while other letters retain their math symbols, which definitely is the worst choice.
Same goes for the Colevrak kit. Perhaps it would be best to do "full alphas" Dvorak-cadet and Colemak-cadet kits, instead of a simple differential kit?
Heck, that last bit actually goes for ALL alpha possibilities (language-wise and QWERTY/nonQWERTY-wise), come to think of it.
