yes, but this is what we have already in fido and the others somehow. I
wanted to keep things easier.

Yes, I know, but I shouldn't be able to change the TAB one. BTW in
terminal S-M-C-v conflicts with terminal yank.

This is something simple to implement, but again, this something more in
the icompletes-ivy-ido experience.

Yes but somehow I found more "intuitive" to do it with tab.

Actually it is ESC ESC ESC. C-g was unbind in the Completions
buffer. Doing C-g (go return to minibuffer) and again C-g (to exit
minibuffer) is shorter and more intuitive than q C-g or ESC ESC ESC.

But don't worry this kind of changes I understand they require
discussion in the ML and are only kind of "proposals" to see reactions.

I agree, here. I just ran out of ideas to make it simple and "Intitive"

Yes this was intentional to avoid changing the defaults.
