I wouldn't expect it, nor defaults, to do so; the multis are still subs with
their own signatures. Further, we rely on the ability to not have to really
call an onlystar proto at all for optimization, and since all operators are
multi-dispatch, that's important. Arguably, the use of certain features in an
onlystar proto could add a note to the "potential difficulties", since it's
very likely a thinko.
