Oh, I'm not saying that the assumption is RIGHT, just that the
assumption was made and it exists in the code.  What it means is that
it's not EASY to make this change.  It's not just as simple as
removing the check in the UI.  It's a deeper issue; the whole set of
algorithms need to be re-thunk in order to remove this assumption.

So, the challenge to you is to come up with a patch that does it!
Good Luck!
