Could it be made package-private? I have concerns around the usage of `ThreadLocal` for things that most cases don't need to be thread local. I don't want to give users too much room to hurt themselves because they don't consider that `CommitMetadata` is _only_ threadlocal and then their writes not working properly in the common case of writes without user-side multithreading (e.g. it gets set in one thread somewhere, but another thread is used for commit). -- This is an automated message from the Apache Git Service.
