I get the feeling Apple isn't going to fix the swap issue anytime soon. I don't think they're being insidious about it, though: the BSD memory model is (arguably overly) complicated, and refactoring any portion of it's memory management is guaranteed to be a pain in the ass. The TL:DR is that MacOS doesn't virtualize memory, and when that memory is unified it will frequently spill over into the swap storage. I have no idea how Apple can pull themselves out of this one, and I have a sneaking suspicion that the swap usage will only increase as time goes on.
