No. Python 2.6 doesn't implement PEP 3137, and the PEP doesn't claim
that it would, nor do the 2.6 release notes. So that it deviates from
PEP 3137 is not a bug.

That's not true: if I write
if isinstance(x, bytes):
one_thing()
elif isinstance(x, unicode):
another_thing()
then 2to3 will convert it perfectly. 2to3 couldn't have done the
conversion correctly had I written
if isinstance(x, str):
one_thing()
elif isinstance(x, unicode):
another_thing()
So the introduction of the bytes builtin *does* help the supposed
point of 2.6, even though it doesn't help implementing PEP 3137.
