It doesn't matter.  I'm saying that we shouldn't name them as a matter
of principle, so as to avoid the few pitfalls you've mentioned, like
talking about non-free repositories.

We could, for example, say something like

  Info manual for Emacs was not found; consider installing it.

which would be more explicit and clear, I think.

It comes from Info-find-file.

Which is why I suggest not to name them.

We could indeed decide that it's not our problem.  In fact, the
current situation is tantamount to doing just that.
