My biggest concern with numpy 2.0 is the new Python integer handling that can cause problems

>>> import numpy as np
>>> np.arange(4, dtype='u1') * (-5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python integer -5 out of bounds for uint8
>>> np.arange(4, dtype='u1') * 1247
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python integer 1247 out of bounds for uint8

Hmm.. I don't have an overview over the codebase, but to me this does not look like a hard blocker, but more like an opportunity to introduce some checks and explicit casts to make the code more stable.
