Maybe I should clarify in the PEP 587 Rationale what are the use cases for
the API. Embeding Python is one kind of use case, but writing your own
Python with a specific config like "isolated Python" or "system Python" is
also a valid use case. For a custom Python, you might want to get C locale

For the PyMainConfig structure idea, I cannot comment at this point. I
need more time to think about it.
About the "path configuration" fields, maybe a first step to enhance
the API would be to add the the following function:

The purpose of the PEP 587 is to have a working document so everyone
can look at the proposed API (stay focused to the API rather than
bothering with the implementation). IMHO it's now time to get more
people looking at the Python Initialization.

That sounds like a potential regression. Those two features were

Ah, I forgot to say that a major enhancement for the implementation is
that I wrote a lot of new unit tests for the existing Python
Initialization API. Python 3.7 has most of these tests. I wrote even
more tests for my new private initialization API ;-)
I wrote these tests to specify and validate

Would you consider making _Py_UnixMain public as well?
It is useful for high level embedding and not trivial for 3rd parties to
reimplement.
