It seems to me that moving PyObject* to be a handle leaves you in a
place very similar to HPy. So why not just focus on making HPy suitable
for developing C extensions, leave the existing C API alone, and
eventually abandon the existing C API?

I think that's a possibility. I think it's a question for the team here whether that's the long-term goal that we want. If so we can make all of our work head towards that and help out HPy out as best we can.
