I don't remember talking tuner buttons recently.
The set of SE tuners I have is from 2007, but Grover mini, Schaller (well, Fender-branded Ping Well copies) and Hipshot buttons fit them. The Hipshot buttons also fit the old 80's Gotoh set I have, so presumably Gotoh buttons will also work on the SE tuners.
It does not work the other way around though. The SE shafts (and therefore the buttons) are a bit smaller in diameter than these other brands, so you can't put SE buttons on Grover, etc.
The replacements I've messed with all work with a little play, but this becomes meaningless once you tighten the screw that holds the button on.
All this comes with a big fat warning of specs may change, YMMV, IME, I'm just some nerd on the internet...
