+1 for that approach.  Much better to break all of the third-party
code out there definitively than to bet on which attribute people are
going to want to use most commonly.

I'm a little confused as to the status of this patch.  It's marked as
Waiting on Author in the CommitFest application, and the last patch
version was posted in December.  The fact that the new CommitFest
application encourages people to blindly move things to the next CF
instead of forcing patch authors to reopen the record when they update
the patch is, IMHO, not good.  It's just going to lead to the CF
application filling up with things that the authors aren't really
working on.  We've got enough work to do with the patches that are
actually under active development.
