haha, yeah, I actually had the same thought, then I realised that we already had 300 tests that would make it pretty clear this went wrong *AND* we still had the test in `spec_helper.rb` that would give developers a message that their migrations were wrong.  (Same code, not coincidentally.)

So, legit issue, but the confluence of circumstances to trigger it seem so rare that it wasn't worth the bother. :)
