It's easy to say that, but those apps are how most Hivers interact with the blockchain. Delaying a couple of days is worth it, IMO.
And we also can't be sure they won't find real problems with hived/hivemind, when they do their testing. We've been developing automated tests as rapidly as we can, but there's a huge number of Hive API methods to test. At this point, the largest set of "tests" is the Hive apps themselves.
