;TLDR Embedded LO python will never be standard so DOCUMENT IT so users can
work with it, include pip as in a standard install (likely in an admin area).
Someone getting a non-standard undocumented feature to work means no more than
it can work.

Why? V7.2 is pre-release. V7.0 is still available. How are users expected to
deal with the issue?

LibreOffice 7.2.0 - If you're a technology enthusiast, early adopter or power
user, this version is for you!

LibreOffice 7.1.5 - This version is slightly older and does not have the latest
features, but it has been tested for longer. For business deployments, we
strongly recommend support from certified partners which also offer long-term
support versions of LibreOffice.

Available Versions - LibreOffice is available in the following released
versions: 7.2.0, 7.1.5, 7.0.6

> PS C:\Program Files\LibreOffice\program> .\python.exe C:\Users\Pruebas\get-pip.py --user

Where is *that* documented? I never have any need for powershell.

Problem: Installing packages is essential for more than trivial python use yet
there is no documentation

Issues are:
* Clear user documentation should be available. Pip maintainers say their
documentation can't be followed because the LO python package doesn't include
pip - pip should be part of embedded python.
* It is not uncommon for users to have python installed on their system. How
can a user work with the specific version they need to? How does a user even
know where LO embedded python is in eg "C:\Program
Files\LibreOffice\program\python.exe" or is that "C:\Program
Files\LibreOffice\program\python-core-3.8.10\bin", or perhaps
"C:\Users\User\AppData\Roaming\Python\Python38\Scripts"?
* Related issue is should LO python be in a venv as in other software where it
is embedded?

1. What documentation are you referring to?
2. Version information above. 7.0 is an available version. How are users
expected to know how to deal with this issue?

LO has no docs for installing packages or pip. I followed the link given to the
official pip docs.
"And -m ... This would never work" - that's my understanding of the pip docs.
Who knows why you chose those commands, I showed my workflow clearly rather
than just the commands that worked.

I'm an ordinary user and I followed official pip docs. iirc I installed with
and without admin rights during testing but I can't recall which one I
documented here. Should be without admin rights.

Again, where are the docs?

*Document it* and make pip part of LO embedded python.
