Merge Queue

This is a list of outstanding work and related PRs in the order we currently plan to merge them to unstable. Tasks should be picked up loosely in this order, and PRs for tasks should be built on top of PRs that precede it.

1. New containers and container modifications
2. Payload Processing modifications
3. Fork choice modifications
