Correct.

Yes, this should work. (I thought it already did but was wrong. ;-)

Correct.

Right.

I'd rewrite this as follows:
C name | 2.x | 3.0a1 | 3.0a2 |
----------+--------------+------------+---------------------+
PyUnicode | unicode u"" | str "" | str "" |
PyString | str "" | str8 s"" | bytes "" |
PyBytes | N/A | bytes b"" | buffer buffer(b"") |
----------+--------------+------------+---------------------+
Seems worth adding to the PEP. I'll do that.
