Please add a way to semi/fully-protect the board description.
Because, some board descriptions get improperly used as a sandbox, or for spam, a lot.
E.g. (ctrl-F for "description")
For context, it is currently possible to protect the full board, but not just the description.
We can do this by reusing the existing MODERATED_LOCKED state, adding a new right (flow-lock-header) (flow-lock is given out to all users), and adding the UI. This would provide for full-protection.
