In the case of the package upstreams being responsive I will work with upstreams to fix (a bunch of fixes already in progress). If the upstream is dead I will work with the Fedora maintainers to work out what they wish to do. There's a couple of packages that I don't think actually work with pandas 2.x, there were changes/deprecations in 2.x to prepare for the 3.x release, even though they build against pandas 2.3.x and I suspect those packages are broken and likely aren't used. > Has compat been tested in Copr or such?

Yes, there's a pandas3 copr referenced in the change in the testing section ;-) A bunch of the current broken should be fixed with the pandas 3.0.1 release due this week. I will do another rebuild in copr once that is tagged.
