There seems to be some confusion here, as Bug#28156 does not propose any
change to how make-symbolic-link's 2nd argument works, (expand-file-name
linkname) in this case. If the 2nd argument specifies a remote name, as
in your example, then Tramp will take over and do whatever it wants with
both arguments, so Bug#28156 is not proposing any change there (although
perhaps some changes would be helpful for consistency, that's a
different matter).
Bug#28156 is proposing changes only when the new linkname is local, and
in those cases, if I'm not mistaken, Emacs currently errors out when the
target looks like it is remote, so Bug#28156 is merely proposing an
extension. Emacs routinely creates dangling symlinks with targets
containing unusual characters like ":", and it wouldn't be surprising if
users wanted to do something similar on their own.

That's fine, as Bug#28156 is not proposing any change here. LINKNAME
continues to be treated as a file name under the proposed change. The
proposed change affects only symlink contents, not symlink names.
