LGTM but I'd say we should hold off merging this a bit until other open PRs get merged to avoid merge conflicts.

• Deprecations for v2 upgrades #154
• remove kv stores from install.py #156

I see pre-commit.ci is already configured to run for this repo at #156 now btw, so the work for this PR can be as simple as git checkout main, git pull, git checkout autoformatting, git rebase -i main and then delete the pick <commit that ran pre-commit>, git push --force

I mared this as draft to signal its good to go - but pending.

One little comment about excluding versioneer's file from autoformatters (feel free to switch to tbump instead, if you want), but should be ready now
