What about "abcdef^A^B"?  Does M-f stop before the control characters?

I guess I don't understand the rationale for the change.  Categories
are Emacs's invention, and their purpose is mostly to allow us to use
regexps for searching certain characters, and other similar
subtleties.  Your rationale seems to be some attempt to be formally
"consistent".  But this is not a formal attribute, it is entirely
ad-hoc, as can be easily seen by just looking at the list of the
categories.

So I wonder why would we want to rock that particular boat.
