No. There is never a way to go back. Once a kernel is updated, you're stuck with it until the next update. That being said, since this is being pushed out to some people OTA, there will be a path going forward as it's going to have to be considered "official".
Ok, that is in line with my thinking. I have very frequent data drops regardless of geographic location (east coast, west coast, name it). VZW tried a refurb phone which was even worse so I'm thinking of just doing the update manually as there seems to be very little downside, unless I'm misinterpreting something.
