@weiji14 when do you think we can merge this? not a blocker just wanted to merge your branch into the PR I'm working on but my PR goes to a branch so no worries.

[weiji14]

I was gonna wait for @JessicaS11 to merge #622, and then we can merge this to have 3 Python versions supported at least (3.11, 3.12, 3.13).

#622 is merged; this looks good to me. r.e. #569, should we add a note to the docs around SPEC0 to this PR?
