For the sake of brevity all subtrees are not explicitly listed. Due to the size of this repository, the natural changes in focus of maintainers over time, and nuances of where particular features live, this list will always be incomplete and out of date. However the listed maintainer(s) should be able to direct a PR/question to the right person.
