​I assume the concept of a main interpreter is inherited from the previous
levels of support in the C API, but what exactly is the significance of
being "the main interpreter"? Instead, could they just all be
subinterpreters of the same Python process (or whatever the right wording
would be)?​

It might also be helpful if the PEP had a short description of what are
considered subinterpreters and how they differ from threads of the same
interpreter [*]. Currently, the PEP seems to rely heavily on knowledge of
the previously available concepts. However, as this would be a new module,
I don't think there's any need to blindly copy the previous design,
regardless of how well the design may have served its purpose at the time.
