Almost completely right. Technically the ABI for the normal ABI is
also something like cp33d (d = "with debug"). The scheme is supposed
to be similar to the filenames inside __pycache__ and of C extensions
and is backported to Python 2.7. We don't generate these correctly at
least for Python 2 in the wheel reference.
