I'm sorry, you're right.
A friend had a problem a couple years back but on review, I see the
script was loading her init file, which require'd vc-hooks. So VC
hooks are not going to affect carefully written batch programs, as far
as I can see.

I'm thinking specifically of using `find-file' on what you think is a
non-existent file, and discovering that the buffer has non-empty
content because the file has been checked out of RCS. I would not
call that "explicitly calling VC functions".
