With every large source of text we will have a specific keyboard layout to type most efficiently.
Colemak is just one of several millions of keyboard layout that fits the bill.
For fixed ZXCV and perhaps fixed QWA position, Colemak is still one of a few thousands keyboard layouts available.
All of them are better than Qwerty and have less than 1% difference in typing efficiency between them.
To switch between them require a lot of relearning though, so people tend to stick to just one of them and forget about others.
