I'm a little surprised that you don't appreciate how other people (such
as me) work, and that you seem to regard restarting Emacs as a perfectly
acceptable way of reversing M-x c-ts-mode.

(Some) users will not be satisfied with a single switch to c-ts-mode,
they will want to move backwards and forwards to and from CC Mode IN THE
SAME EMACS SESSION, and will resent continually having to restart Emacs
to do so.

This "moving backwards and forward" is asymmetric.  It is far, far
easier to switch into c-ts-mode than switch out of it, and I feel this
is not right.  It is why I proposed c-make-ts-undefault-mode.

Also, restarting Emacs will NOT restore auto-mode-alist, unless the user
doesn't use desktop, or somehow knows (how?) he must clear his desktop
of c-ts-mode buffers before restarting.  I foresee much wasted time and
frustration resulting from this.
