This was not directed at you in particular, indeed.

Right.

Yes, but for things which are conceptually global (e.g. all the Qfoo
thingies, which by convention share namespace with Elisp's), the fact
they are currently only accessed from a single file doesn't mean it will
(or even should) stay that way, and adding "static" when that changes is
pointless (and just means we'll have to remove that "static" next time
it changes).

Yes, that's better.
