From my perspective, the difference between LC_COLLATE and LC_CTYPE is
that LC_COLLATE has a quite limited impact area. Either your code uses
strcoll() (or strxfrm()) or it does not. And if it does, you can find
all the places and adjust them, and it probably won't be that many
places. The impact area of LC_CTYPE is much larger and more complicated
and possibly interacts with other settings and third-party libraries in
ways that we don't understand yet and might not be able to change.
That's why I'm more hesitant about it. But I don't see any reason to
keep LC_COLLATE set going forward.
