No reason at all, that was a mistake, I apologise. I hope you don't mind me forwarding this to the list.

Your site-lisp won't, but the one in ROOT/share/emacs will.

Then why do you need separate trees?  That's the only reason why you
need the site-lisp outside of the Emacs tree.  Use the Posix-standard
structure and one root for all the Emacs installations, and the
problem is gone, because you have the common site-lisp directory in
ROOT/share/emacs.

You mean, you will never uninstall?  Then why do you keep the versions
separate?

Well, maybe I'm the only one who works on so many platforms.

It's not wrong as long as you keep all the installations under the
same root, like /usr/local on Unix.

Yes.  Imagine that your --prefix is on a networked volume that can be
accessed from Windows and Unix systems alike.  Then only the
architecture-dependent files (binaries) need to be separate;
everything under %emacs_dir%/share/emacs/ can be installed only once
and used by Emacs from any OS.
