Please, please, can we have typedef names for these signed types that
are supposed to only have values >= 0 ? I object to losing information
that is important for reviewing the correctness of the code and of
future modifications.

Refer to this thread, where I voiced this objection first:

Then it sounded like you had understood my arguments, and we only need
to pick a good name:
