The change is a fairly radical new approach, and there could still be
bugs in the new code, or unforeseen problems.  But in principle, I have
nothing against merging it into emacs-25.

I honestly don't think this change is going to speed up CC Mode very
much at all.  A little bit, perhaps, but not very much.  For example, in
Martin's `foo' and `bar' (defuns which do `beginning/end-of-defun'
repeatedly) traversing xdisp.c, there was a saving of 6 - 8 seconds in
each direction, but the real time sink was checking for K&R
declarations in the backward direction.
