I don't see in which way this is different for cc-mode than for any
other major mode.

Indeed, currently it can only be enabled globally.  But it can be
disabled per-buffer.
I haven't heard any complaint about it from users yet.

I'm not sure that would prevent cc-mode from obeying electric-indent-mode.
