Well, it's a hack, but you can avoid the Oculus updates. I've blacklisted all the Oculus .exe's in my firewall precisely for fear that an update will break the DK2 compatibility. I'm on Oculus 1.5 and actually, I'm using the DK2 clone, Deepoon HMD which has DK1 and DK2 modes.
Oculus home starts up fine and I can play ED, Alien Isolation and Skyrim with no problems, but of course, I have an error message in Oculus Home saying it can't connect to Oculus server. Not an issue for me since I don't use any of the features of OH. I realize some have purchased games through OH and probably can't use this hack or else they may not be able to play their games.
I've also cloned my SSD in case something tragic happens I can revert back to my previously working state.
YMMV
