Right. If it wasn't I wouldn't have proposed the change.

Considering that local_t has been broken so that basically nobody
is using it, now is a great time to rethink the types before it
gets fixed and people start using it.

And modelling the type on the atomic types would make the most
sense because everyone already knows them.
