Comment (by thoughtpolice):

 Right, but as I said before, this release simply added instances - which I
 think ''is'' a minimal burden (via `MIN_VERSION_transformers` or whatnot).
 Of course, people are free to disagree.

 If it was a bugfix release, I'd probably feel differently (indeed,
 `binary` underwent a bump for 7.10.2 precisely because it had 2 real
 bugfixes). But here I don't think a bump is really necessary for a minor
 orphan addition in this case.
