Of course we do: with-temp-buffer produces buffer names that follow
such a template.

Such buffers should not necessarily be exempt from running the hooks,
AFAIU.  In any case, one can always bind the hook locally to nil in
the body of the macro, right?

I think this is too drastic a measure.  We should only disable the
hooks in buffers where no one in their right minds will ever want to
run them.
