I was not arguing about the rewrite when the target is
/sameuser@samehost:/destina/tion an error because there is no way to make a link to
the local machine's disk".

I don't like the rewriting, but I can live with it.  OTOH, raising an
error just because Emacs thinks the operation doesn't make any sense
would just be wrong.  Especially since it's not trivial for elisp code
to transform "/destina/tion" into "/sameuser@samehost:/destina/tion".
