Kaby Lake: I recently replaced my laptop, and I'm not looking to replace my desktop.
Windows 10/Edge: I've got a license and a backup image containing the install, but I don't intend to use it.
Premium account: Meh. It's just me and my wife, and we don't have anything over 1080p. No point.
This reminds me of the Vista-only release of Halo2, when Microsoft insisted that there were technical reasons that it couldn't be made to work on XP. Then someone overrode the OS version checks and it worked fine.
