True.  You'd have to do a bit more work to find the correct workspace if
that's not the case.  But there's a nasty stinger in that tail:  if you
send a message to a workspace that is not current, the message won't
actually be sent because workspace operations require access to the
display, which can only be granted if the workspace is current.  So if it's
not the current workspace, you lose anyway.  There's no way to make it work.

And no, you can't approach it from the other direction, either; a different
version of the same problem gets in the way.  :/

(I recently filed a bug about the design issue that causes this.  It won't
be easily fixed.)
