Maybe I'm missing the obvious, but if you need indefinite long-term support of Python packages why don't you use the conda-forge distributions https://github.com/conda-forge/htcondor-feedstock?  (Also props to Duncan, that feedstock looks very well maintained.) Conda-forge is immutable and so those distributions will be up and usable for as long as conda-forge is (and it isn't very hard to create a mirror of (some or all of) conda-forge if you want to have your own long term sustainability backup plan).

Best,

Matthew

We already keep the latest patch release for each LTS series for as long
as possible. In PyPI right now:

23.0.28? Aug 21, 2025
10.0.9??? Sep 28, 2023
9.0.17??? Sep 29, 2022
8.8.15??? Aug ? 3, 2021

The last patch for HTCondor 24.0 will appear sometime next year and that
will be retained indefinitely.

So, yes, any 24.0.x fits the definition of a compatible release.
