Re: Official port of Python on EDK2

[Thiebaud Weksteen <tweek@google.com>]

Christian, Antoine, Brett: Thanks for the clarification on what an official
support would require. As Christian mentioned, sending simple headers
patches is an obvious starting point, no matter if the support becomes
official or not.

Brian: Thanks for your email. As I suggested, by having the support
directly within the Python community, you would avoid having to maintain a
separate port. I don't think that having a new Python3 port as part of EDK2
is a good idea. What I am suggesting is that Intel should contribute
directly to the Python repository by sending your modifications upstream
and not expect someone to re-import Python into EDK2. That is, bringing
your UEFI experience to Python and not the opposite. This would be a much
better use of anyone's time.

Thanks,
Thiebaud
