SGTM - this'll be an ABI break, of course - but we don't have an ABI stability between releases, so I don't think this would adversely affect anyone. We just have to be consistent within a release or version, and we were consistent (though inefficient) before this patch and we'll be consistent (though more efficient/lower memory usage, etc) afterwards.
