Good point, indeed.  This problem already exists in theory in some
systems (such as Debian in the past) where byte-compiled files were
placed in a different directory (for the case where several major
versions of Emacs are used, with packages re-compiled separately for
each major version).

But yes, this will bite much more often.

We could lie (set `load-file-name` to point to the source file, for
example) or introduce some function to go from the `load-file-name` to
the "intended" origin (something like the name of the source file) and
update all packages to use that function?

I assume that was a typo, I didn't see nay Stephane in the Cc.
