This is an important question that needs an answer.

As would I, but for a different reason: I put CTRL under my left
thumb, so C-z is a very convenient prefix for stuff I do all the time.

I strongly dislike differences in keybindings between gui and
non-gui. Just look at all the questions that come up about org-mode
because some of its commonly used keybindings donʼt work in a terminal.

Iʼve never used two column mode, it would be nice to have F2 bound to
some useful functions. Iʼm not sure what TV had in mind here.
