LGTM. Just since I was not aware, SPEC 0 argues for a 3 yr support window for Python versions, and 3.10 came out toward the end of 2021.

Originally, astropy was following NEP 29 which has a slightly different schedule. However, it now follows SPEC 0 as recommend by numpy itself. Since one of our core dependencies is astropy it makes sense for us to follow the SPEC 0 schedule along side astropy.
