This clearly isn't called for in this case. We're talking about a
single function on a collection. In this case, importing an
alternative set API (and maintaining the dependency) is more work than
just writing your own workaround. The purpose of adding a method is
to prevent the need of everyone writing their own workaround.

Clearly, I'll need to write up the PEP.

I doubt some of the people on either side are going to be
convinced. I'd settle for convincing most of the fence-sitters, along
with a few of the loyal opposition.
