Well, when the code is committed I will update the porting HOWTO and push the future imports first since they cover more versions of Python (i.e. Python 3.2). But I will mention the options that skip the future imports for those that choose not to use them (or have already done the work of using the u prefix in their code). Plus that doc probably will need an update of caveats that seem to bit everyone (e.g. the str(bytes) thing which I didn't know about) when trying to do source-compatible versions.

See, I think the emphasis should be on using the future imports and unadorning your unicode literals. Forget about this PEP except as a footnote. This strategy works today for most packages. You might think that this is ugly, but really, I think that doesn't matter (or maybe better: get over it! :). Definitely don't let that stop you from porting now.

In the small minority of cases where this strategy cannot work for you (and I admit to not really understanding what those cases are), then the footnote about the reintroduction of the u-prefix should be enough.

And yes, the str(bytes) thing is a pain, but it too can be worked around, and is such a minor wart that it should not delay your porting efforts.
