Why exactly is that?

We should take an attitude that Python hash values
are completely arbitrary and can change at any point
without notice. The only strict requirement should be
that hashing must be consistent with equality; everything
else should be an implementation detail.

With that attitude, supporting explicit seeds is counter-productive.
