statsmodels fails completely to import with scipy 1.16 (from
experimental).
e.g.

 81s /usr/lib/python3/dist-packages/statsmodels/distributions/discrete.py:5: in <module>
 81s     from scipy._lib._util import _lazywhere
 81s E   ImportError: cannot import name '_lazywhere' from 'scipy._lib._util' (/usr/lib/python3/dist-packages/scipy/_lib/_util.py)

The problem is fixed upstream,
available in upstream release 0.14.5.

This bug will become RC serious later, once scipy 1.16 is uploaded to
unstable.

Control: tags -1 pending

This version is in Salsa, though I haven't tested it with scipy 1.16.

Do you want it in experimental now, or should it wait until the release
and go to unstable?

No great rush on it, it's fine to wait until trixie is released.
