I agree that these are totally unrelated issues.

After all, Jonathan's suggestion to forbid it was because the
combination does not make sense and does not have practical uses,
and forbidding it would make the command easier to explain than
leaving it accepted from the command line.  If you choose to go in
the opposite direction and make "clone --bare --separate-git-dir" do
something useful, it should be explained very well in the
documentation part of the patch why such a combination is a good
idea, and in what situation the behaviour is useful and the user may
want to consider using it, I think.
