Well, not quite. The core complains about it nowadays, but does not
reject messages. It will try the same behaviour as before. It will just
inform the user that somethings is tried which may not work. I probably
should update the error message printed saying that the transfer is
still tried.

Given my reasoning above, that should have happened before the warning
was printed as well? Because same behaviour. I'd be surprised if there
was a change...
