On my own account as I don't have the Dogecoin password on me - it's a way of allowing users to create their own hard forks, and as with any hard fork whether it's adopted or not depends on consensus. Essentially a lot of proposed changes we don't try, because we're fairly certain that we can't get consensus on them (and/or they're just a bad idea), but we shouldn't be the gatekeepers for changes, the community should. So if someone can get consensus on a new hard fork, and get enough people to adopt their suggested configuration, it should become the new main fork.
