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.
