Yes, sorry, I meant C-c ' and C-c `.

Binding C-c ' by a major mode defies the convention.  Whether
you want to interpret the convention as a prohibition (without
any real teeth) or just a mild discouragement is up to you.

What we can say is that any major mode that binds such keys
does not respect the GNU Emacs key-binding conventions, which
were defined to allow help modes and libraries cooperate.
There can be no disagreement about that.

We can disagree about how important it is to respect those
conventions.  Icicles, at any rate, does respect them.

It's not about me or my code or being allowed.  C-c ' is
reserved for minor modes.  Any minor mode can bind such keys.
No major mode should do so.
