In principle, yes. What's the cost of the additional field in terms of
a size increase? If you just need another bit, could that fit into
_PyUnicode_TypeRecord.flags instead?

That would be best. You only need to include the patch to the generator,
not the generated data. I'd like to see it in 2.6, so ideally, you would
test it for the trunk (not that the branch should matter much)).

Don't forget to include test suite and documentation changes.
