[Q] upgrade, root, warranty void fix? topic

Is there a fix, in the works, similar to triangle away, clear cache partition for 4.4.2 like for 4.3? A Knox fix I guess? I've already jumped the gun, and updated OTA. And I'm a little hesitant about rerooting, as I read an article that said there is no warranty fix once you root from 4.4.2. Anything?
