If I'm not mistaken, C-C, C-X, C-V came from windows, or maybe DOS. A lot of Unix editors are older than that, so you can't blame them for not using those.

A lot of programmers probably don't invest the time to learn an editor, but it not much time in the long run, and it's worth learning your tools.
