Actually, list-load-path-shadows is executed when you install Emacs.

But I think the output gets lost in lots of other output, so it
doesn't help that much.

IMHO it would be useful to make that output more prominent.

Doesn't Emacs include a versioned site-lisp directory in the
load-path by default?  So the installation instructions could suggest
to use that for such cases.  But it could be that the directory is in
load-path only for versions > 21.3.
