Checklist

• All new code is appropriately documented (user-facing code must have complete docstrings).
• Added a news entry, or the changes are not user-facing.
• Ran pre-commit by making a comment with pre-commit.ci autofix before requesting review.

Manual Tests: these are slow so don't need to be run every commit, only before merging and when relevant changes are made (generally at reviewer-discretion).

• GPU integration tests
• example notebook testing
• packaging tests: run this for any large feature PRs or PRs that add test data.

One question I have on this before we review is whether we should be scoping tokenizables that each store can hold? My guess is yes, but I wasn't 100% sure. Either way, figured I would get this out so we can start the process here.

We may need to rebase the base branch so that tests can pass since they don't seem to be because of me.

In discussion with @atravitz we need to cherry-pick this into two PRs rather than keeping it monolithic.

@atravitz I removed the testing commit and this commit now blocks #1809 from merging, we are now ready for review.
