No it does not.  The issue is that this is a trap waiting to spring and
bite hackers.  Also the workaround you identify is ugly and irregular -
it would involve writing two format strings (one of them being the "%s")
to do one `message' invocation.

I have identified a regular and rational way to repair the damage,
namely to introduce the new %-constructs %` and %', which would invoke
quote translation, and would remain compatible with `message' as it was
before Emacs-25.
