Please do not exaggerate. I want you to look at the keys reserved for
major modes!

Why? This just looks like a rant.

We have different opinions. Saying that it is an excellent choice is
an exaggeration. It is not an excellent choice in my opinion.

That would be nice, but would not that mean that all key bindings
should be changed when cua-mode is on? Or do you think CUA land is
outside of Emacs?

All C-x bindings are absent from that page. I guess you do not mean
that a major mode could use any key bindings starting with C-x?

I have assumed that C-x is not mentioned because it is reserved for
Emacs. If not, then it should be mentioned on that info page to
clarify things.

But my opinion is very clear: Recommend that 3rd party libraries
should not use C-x as a prefix key.
