Cython 3 is already in unstable; pandas is currently using cython-legacy.

And yes, my list of packages broken by pandas 2.x is those identified by builds and autopkgtests.

up to the maintainers. But please wait at least until the current pandas and numpy migrated to testing, e.g. that the autopkg tests of pandas and numpy triggered by python3-defaults pass.

I just nmued pyrle and sorted-nearest, having dependencies on cython3-legacy, letting the pyranges autopkg tests fail. Once this succeeds, pandas should be able to migrate.

pandas' testing migration is also blocked by its build-dependency on python-xarray, and xarray's on python-sparse and cfgrib.

If necessary, pandas can be built without xarray, but this skips some tests and probably adds some error messages to the documentation (the examples are run at build time).
