For personal scripting, we can install whatever, but "institutional
scripting" isn't the same thing - there we're scripting predefined
"Standard Operating Environments", like those Mahmoud Hashemi describes for
PayPal at the start of
"Just use PyInstaller" isn't an adequate answer in large-scale environments
because of the "zlib problem": you don't want to have to rebuild and
redeploy the world to handle a security update in a low level frequently
used component, you want to just update that component and have everything
else pick it up dynamically.
While "Just use conda" is excellent advice nowadays for any organisation
contemplating defining their own bespoke Python SOE (hence Mahmoud's post),
if that isn't being driven by the folks that already maintain the SOE (as
happened in PayPal's case) convincing an org to add a handful of python-dev
endorsed libraries to an established SOE is going to be easier than
rebasing their entire Python SOE on conda.

Yep, that was my intent, although it may not have been clear in my initial
proposal. I've filed two separate RFEs in relation to that:
* Documentation only: https://bugs.python.org/issue31898
* Regression testing resource: https://bugs.python.org/issue31899
