Maybe you're right.

inhibit-read-only, bound nearby, seems to be in the same situation.

You're right, and that sounds a little too complicated for my taste.

So, personally, I'd try to fix the particular instance first. Switching 
buffers inside with-silent-modifications is not a very common usage, I 
think.

Maybe org-src should itself let-bind the aforementioned variable(s) 
where it visits other buffers.

Up to you, of course, since you've already been given the go-ahead for 
the proposed fix.
