[Meta] create policy around locking of conversations

As pointed out in #1472 (comment), it would be helpful for the maintainers of this repository to have a documented policy for when (if ever) it's suitable to lock conversations. Such a policy would ensure consistent and fair use of the locking feature. This issue tracks the task of creating that policy.

I'd rather not interfere with people's commenting, it's gonna be hard.

What we really need is: #601 and #1008 :-)
