Not necessarily. They may have approval for the latest approved vendor
software, but not for third party packages.
Nick has been quiet lately, it would be good to hear from him, because I
expect Red Hat's corporate userbase will be an informative example. I
hear Red Hat has now moved to Python 3 for its system Python, so I
expect that many of their corporate users will be, or will soon be,
running Python 3.x too.
In any case, it's not the users stuck on 2.6 *now* that I'm so concerned
about, since as you say there's nothing we can do for them. Its the
users stuck on 3.9 ten years from now, who are missing out on
functionality because we keep saying "its easy to get it from PyPI".
(To be clear, this isn't a plea to add everything to the stdlib.)

Indeed, it isn't easy to know where to draw the line. That's what makes
the PyPI argument all the more pernicious: it makes it *seem* easy,
"just get it from PyPI", because it is easy for we privileged users who
control the computers we use.

The node.js world is hardly the paragon of excellence in software
development we ought to emulate.

Arguably, modern software development will have to slow down and stop
introducing a dozen zero-day exploits every week. (Only half tongue in
Browsers are at the interface of the most hostile, exposed part of the
computer ecosystem. Not all software operates in such an exposed
position, and *stability* remains important for many uses and users.
I don't see that this is really relevant to Python though, not unless
you're thinking about accelerating the pace of new releases.
