Sorry for the confusion. I forgot that there are different readings of NEP29 and that this lead to misunderstandings before. The proposed policy is that all python versions supported by NEP29 are also supported by sage (this is the lower bound) and that we normally drop support for older versions right after this support window (i.e. also adapt the drop schedule https://numpy.org/neps/nep-0029-deprecation_policy.html#drop-schedule). I've formulated an improved formulation for this policy at https://github.com/sagemath/sage/pull/35403#issuecomment-1566110884 which should hopefully clarify this point. (Dropping support means increasing `python_requires` and removing github tests for this old version, i.e. similar to https://github.com/sagemath/sage/pull/35404 which is modeled on the PR drooping Python 3.7.)
