The issue, I think, is with the way the collision detection takes place currently, and is one of the things they've been discussing. Collision detection, however, is probably a lower priority than some of the other issues and enhancements that need to be addressed, just by its nature. Lower altitudes don't suffer the above-mentioned bugs. It's primarily the higher altitudes that do. I wouldn't be surprised to see a generalized "fix" to mitigate it in the interim, but would expect to see something a lot later in the builds to actually address it point-blank.
