He's not complaining about that.  He's annoyed about having removed
%emacs_dir%/../site-lisp from the load-path.

>> c:\>dir /B c:\emacs
>> emacs-111818
>> emacs-112125
>> emacs-112416
>> site-lisp

Except that the site-lisp file now won't be used any more unless you ask
for it manually in your .emacs.

> Did you really have files in "%emacs_dir%/../site-lisp"?

Apparently he did, yes.

No: he specifically wants to share all the external packages under
a single site-lisp.

No, they work just fine as long as the compiler was older than the runner.
