i do not like the idea, people that use X11 are used to have crtl-alt-bs.
it is confusing not to have it. i do not see a real problem.

if xorg is confused to an extend that c-a-b does not work anymore it is clear
that the code may need some improvements.
An other idea would to allow additional key combinations  (mod+mouse) to behave like
c-a-b. looks like a nice config option.
