Any stdlib improvements we discuss and implement today are easily a decade away from benefiting users in restrictive environments. On that kind of timescale, it's very hard to know what to do, especially since, as Paul says, we don't hear much feedback from such users.

As a user in that situation, I can confirm that there *are* situations
where I am stuck using older versions of Python (2.6? Ha - luxury! I
have to use 2.4 on some of our systems!) But there are also situations
where I can do a one-off install of the latest version of Python
(typically by copying install files from one machine to another, until
I get it to a machine with no internet access) but installing
additional modules, while possible (by similar means) is too painful
to be worthwhile. Also, when sharing scripts with other users who are
able to handle "download and run the installer from", but
for whom "pip install" (including the proxy configuration to let pip
see the internet, which isn't needed for the installer because our
browsers auto-configure) is impossibly hard. So "latest Python, no
PyPI access" is not an unrealistic model for me to work to.

I can't offer more than one person's feedback, but my experience is a
real-life situation. And it's one where I've been able to push Python
over other languages (such as Perl) *precisely* because the stdlib
provides a big chunk of built in functionality as part of the base
install. If we hadn't been able to use Python with its stdlib, I'd
have probably had to argue for Java (for the same "large stdlib"

I'd dispute that. It's increasingly at odds with how *open source*
software, and modern web applications are written (and my experience
is just as limited in the opposite direction, so I'm sure this
statement is just as inaccurate as the one I'm disputing ;-)). But
from what I can see there's a huge base of people in "enterprise"
companies (the people who 20 years ago were still writing COBOL) who
are just starting to use "modern" tools like Python, usually in a
"grass roots" fashion, but whose corporate infrastructure hasn't got a
clue how to deal with the sort of "everything is downloaded from the
web as needed" environment that web-based development is embracing.

> Browsers and Rust are updated every month. The node.js world is a frenzy of change. Are these users' environments running 5 year old browsers? I hope not for security's sake.

For people in those environments, I hope not as well. For people in
locked down environments where upgrading internal applications is a
massive project, and upgrading browsers without suffcient testing
could potentially break old but key business applications, and for
whom "limit internet access" is a draconian but mostly effective
solution, slow change and limited connectivity is a practical

It frustrates me enormously, and I hate having to argue that it's the
right solution, but it's certainly *not* as utterly wrong-headed as
some people try to argue. Priorities differ.

> At some point, languorous corporate environments will have to catch up to how modern software development is done to avoid seriously hampering their employees' effectiveness (and security!).

And employees making a grass-roots effort to do so by gradually
introducing modern tools like Python are part of that process. Making
it harder to demonstrate benefits without needing infrastructure-level
changes is not helping them do so. It's not necessarily Python's role
to help that process, admittedly - but I personally have that goal,
and therefore I'll continue to argue that the benefits of having a
comprehensive stdlib are worth it.
