Rules (WIP):

• If something is completed, just marked
• If there is a PR/Issue/Discussion please add it (try to use one item)
• If there is someone taking ownership on it, please add it. Ownership means to be the focal point for it not necessarily the person who makes the final change.
• If there is no leader, feel free to claim it.
• If you can no longer lead something, just let others claim it back
• As this issue can have many comments, feel free to address them and then mark the original comment as "outdated" (details) so it is easier to follow.
