I think there is something to lose though. Aside from being a waste of time, it's a waste of user goodwill. We've already seen how momentum for this stuff wanes over time. If you wait too long before starting the migration process, people just won't be interested. Obviously, it's a gradual thing, but many moderators don't seem to have even started trying.
Which do you think is going to be more effective:
Spamming your sub with John Oliver shitposts, going private occasionally whenever /r/ModCoord says so, and then making plans to migrate when interest has gone down and people have returned to the status quo
