This is a little embarrassing as I've known about these for a while, and a lot embarrassing as I can't fix them quickly because I'm perpetually behind the curve in keeping up with Pandas.

The breaking change is that numpy.argsort used to return a dataframe when given one, but now returns an array. Something relates to __array_wrap__ being deprecated a while ago and now removed, and also relates to the whole __array_ufunc__ mess that might also be ripped out. (The version of numpy makes no difference because it's a matter of what dunder methods pandas provides.)

I'll look into this more tomorrow.

This is blocking Python 3.12 support, since they don't seem to have builds for that combination
