You shouldn't quote someone unless you know he considered all the options. When he posted he probably wasn't thinking about multiplayer spectating. If multiplayer spectating were implemented, then both considerations are a real possibility. Without such an idea, it's highly unlikely it would be allowed. So if we're going to have these ideas at all, they should be used to their fullest extent.
It doesn't need to happen right away. These ideas could be implemented with length restrictions, and then multiplayer spectate can be implemented later on that would remove the need for such restrictions.
