Here, I try to install the pvlib, including the nlr-pysam extra, using Python 3.15, which isn't quite fully compatible due to nlr-pysam and h5py being tardy with the latest wheels.

% uv sync --python 3.15 --no-install-package h5py --extra all
Using CPython 3.15.2
error: The requested interpreter resolved to Python 3.15.2, which is incompatible with the project's Python requirement:
       `>=3.11, <3.15` (from `project.requires-python`)

I'm happy to chase down conda-only test failures, so long as maintainers are ok with the upper bound on Python version.

This is a duplicate of #2872 - without pinning versions. I understand your motivation to pin versions, but I think at this point it is clear that it's just a debate with its own set of technical limitations and maintenance burden. I suggest closing this PR.
