For me, this makes my 60HE borderline unusable for productivity, and very annoying on Windows in any case. I am habitually dependant on being able to perform multi-key chords with a single Fn layer keypress, and on being able to rebind capslock to alt+shift for windows usage with multiple keyboard layouts.
Switching between alt+shift and capslock for layout toggling is legitemately wasting up to multiple minutes of my productive time a day.
And sure, this mostly is on micro$hit for not allowing arbitrary keybinds for layout toggling, but they sure as hell aren't changing that in the foreseeable future.
