I'm not sure why every new layout decides to remove the CAPS LOCK KEY. I imagine coders aren't the inventors of these layouts.

May I infer from your post that you use Caps Lock at least semi-regularly?

Myself, I abhor it. I've always just held Shift, even for long runs of capital letters. As far as my usage patterns go, Caps Lock serves only to foil my attempts to type my password. :/

Colemak provides a Capslock-intact version.
