Mostly documentation stuff, looks good to me overall.

It's worth mentioning that editing flags isn't documented (neither is the permission requirement); still, it works as expected and the client does it this way too.

Should we add it, though?

Seems fine. If anything, the edit parameter wouldn't break, it'd just be ignored; I sincerely doubt they'll change anything about it though.

lgtm, thanks!
