I take back. I've read the commit you've pointed out a few patches
later:

* Property "role" replaced by "master".  role=master becomes
  master=on, role=peer becomes master=off.  Default is off instead of
  auto.

I don't think it makes any sense to expose the old stuff since it does
not work anyways and we never used it apparently.
