I'm thinking it makes the most sense to treat inclusion in the recommended
packages list as a possible outcome of proposals for standard library
inclusion, rather than being something we'd provide a way to propose

We'd only use it in cases where a proposal would otherwise meet the
criteria for stdlib inclusion, but the logistics of actually doing so don't
work for some reason.

Running the initial 5 proposals through that filter:

* six: a cross-version compatibility layer clearly needs to be outside the
standard library
* setuptools: we want to update this in line with the PyPA interop specs,
not the Python language version
* cffi: updates may be needed for PyPA interop specs, Python implementation
updates or C language definition updates
* requests: updates are more likely to be driven by changes in network
protocols and client platform APIs than Python language changes
* regex: we don't want two regex engines in the stdlib, transparently
replacing _sre would be difficult, and _sre is still good enough for most

Some other packages that might meet these criteria, or at least be useful
for honing them:

- lxml
- numpy
- cryptography
- idna
