[Distutils] Q about best practices now (or near future)

I'm going to be pushing an update to one of my projects to PyPI this week and so I figured I could use this opportunity to help with patches to the User Guide's packaging tutorial. But to do that I wanted to ask what the current best practices are. * Are we even close to suggesting wheels for source distributions? * Are we promoting (weakly, strongly?) the signing of distributions yet? * Are we saying "use setuptools" for everyone, or still only if you need it (asking since there is a stub about installing setuptools but the simple example doesn't have a direct need for it ATM, but could use find_packages() and such)?
