SPEC 0 minimum supported python version

[d-v-b]

SPEC 0 recommends that we drop support for a Python version for 3 years after its initial release. That means dropping support for python 3.11 (released on October, 24 2022) soon.

Do we want to follow the SPEC 0 recommendation and drop support for python 3.11 soon? It's just a recommendation, so we have some leeway here.

And if we don't want to follow the SPEC 0 minimum python version recommendation, when would we drop python 3.11? 4 years after release? 5?

I would like to be guided by a signal from downstream projects. If literally everyone downstream has already dropped python 3.11 (big doubt), then we could drop 3.11 painlessly. If nobody is ready to drop python 3.11, then we incur the maximal pain if we drop it. We need to put a decision boundary at some point between these two extremes.

I think at least a few people thought that Zarr-Python follows SPEC 0 since it's listed as an endorser, based on the reactions to zarr-developers/governance#11 (comment)
