Marked as draft for now since I want to get feedback before landing.
Things I'm not sure about:

- I listed myself as "lead maintainer", but I want to confirm with the other people that that's okay before committing to it.
- Are people happy with the categories I listed them with?
- Are there other people who should be maintainers?
- Are the people I did list as maintainers willing to take on the responsibilities listed here: https://llvm.org/docs/DeveloperPolicy.html#maintainers
- Does the rst formatting actually work? I think it should but I need to check.
