Yes. The T_BYTE/T_INT is actually pretty  minor compared to the
underlying issue (where we cast back and forth between int and char).
I will make a new PR that fixes everything but this exact point, and
will put an actual accessor if needed. Given that dtype.flags is
nonsensical as of today (at the python level), I would expect nobody
uses it.
