> The best situation would be PSF hosting continued Python 2-compatible development by people who want to do the work.
For who? This costs the PSF manpower/overhead that they don't want to expend on a thing they don't want to maintain. It dilutes the language that the PSF are stewards of, and would further cause a schism in the python community. None of those things sounds good for python, its ecosystem, or the PSF. They sound good for, like, a few curmudgeonly companies and individuals that don't want to migrate.
I can't parse your first sentence, so I can't respond to it.
For users of the Python 2 language who have a lot of Python 2 code and for whom migration doesn't make cost/benefit sense on technical merits of Python 3.
There's Tauthon. There's Active State's long-term support for Python 2. There's presumably Red Hat's long-term for Python 2. There are probably others. Also, there's the need to keep the server side of pip up and running for these to work.
It would be great if there was a common venue for collaboration for these by the parties who are interested in keeping Python 2 going. (I'm not suggesting that Python 3 core devs should do the work.) Like a foundation for Python software.
The first sentence meant that claiming the command-line executable name python for Python 3 is hostile to letting an execution environment for Python 3 and an execution environment for Python 2 co-exist going forward without having to modify existing programs that assume that python is for Python 2 and python3 is for Python 3.

Yes, but I don't believe I've seen any (real) suggestions to change PEP 394.
> There's Tauthon.
Which I claim is actively bad for python's ecosystem in the long term. It shouldn't be supported by any organization that wants what is best for Python.
> There are probably others. Also, there's the need to keep the server side of pip up and running for these to work.
That works just fine without any help. pypi continues to support python2 tags and wheels, and I doubt that'll change anytime soon.

So the entire reasonable bit here is that the PSF should provide something to help various enterprise companies manage backporting security patches. Which, like, I'm not sure what infrastructure is actually needed for that. They already make security patches public. Unless you're suggesting that LTS enterprise support offerings should co-ordinate additional feature work on python 2, which is both unusual and again I claim actively harmful to the ecosystem.

If you have a large amount of Python 2 code that doesn't make sense to rewrite as Python 3 but does make sense to keep developing as opposed to just keep running as-is, it makes sense to want compatibility-preserving improvements to the language.
That such improvements are considered actively harmful comes from a point of view where there's a top-down imperative to shut down Python 2 in order to make Python 3 succeed. It's not harmful from the point of view of the code people have written in Python 2 being valuable.
The notion that there user community needs to work for Python (by porting to Python 3) and that Python 2 needs to be shut down as opposed to Python development valuing the existing code that had been developed is the core problem with Python 3.

But it really doesn't. If the new features are that valuable, you can convert your code. It's not actually that hard (I have a few 100kloc ported forward now, with millions of lines of dependencies that says so).
