[gentoo-python] Status of Python versions

[Michał Górny]

Hi,

1. Python 3.5 is going EOL upstream in <1 year.  I suppose we'll
be removing it from Gentoo at approximately the same time.

2. Python 3.5 & 3.6 are both security fix only.  We should switch stable
to 3.7 ASAP.  If you have a stake in this, please test it and let us
know if there are any deal breakers.

3. 3.8.0 was released, and traditionally our patches don't apply.
If someone feels like rebasing them and bumping it, that would be cool.

4. There's the open question of switching USE flag from 'python3_8'
to 'python3-8'.  The latter gives us a chance of getting rid of
underscores in ~5 years (that's my guess).  We can make the eclass
implicitly translate between '_' and '-' everywhere to avoid making
the API irritating.

5. Python 2.7.  With the EOL postponed, it seems some people are pushing
even more aggressively towards killing it.  I think we'll stay with
the pragmatic approach of leaving it working as long as upstreams
support it but removing it whenever stuff is dead or semi-dead.

6. Do we really care for gentoo-python@ ml?  It's one mail every few
months, so I guess we could just spam the generic -dev list instead.
