I tend to agree.  We can discuss the specific needs that triggered
that request, but by and large, we have a good reason to have
inhibit-modification-hooks that affects any Lisp program that wants to
know about buffer modifications.  That's the difference between the
Lisp level and the lower-level code in C, which "knows everything",
including when it isn't safe to use some data or some objects.
