AFAICT we're only talking about one special case: running from source. I
can't see why Emacs couldn't handle that one special case (and prefer
the source tree to `configure'd paths), but I guess the only way to
really know is to study the source code, indeed.

You mean you then copy the files back into VCS to track the changes?
That's simpler?

Anyway, in such a case I see no ambiguity: you're running the installed
emacs, accessing the installed data files as `configure'd.
