I feel you in the pain of dealing with interlacing, but Carmack was envisaging a more flexible solution than plain two up interlacing. In particular his solution also made HDR imaging possible, which sounds like a worthwhile win to compensate for the pain of interlacing.

Patents for interlaced HDR techniques are out there for the capture chain and probably for the display side also. I think it's premature to take everything Carmack suggests as solutions as gospel as to how things will end up. Speaking from alot of experience in straddling software and cutting edge hardware development, solutions that make sense on one side often come out differently on the other side. And sometimes the best solution is biting the bullet and doing it right without the hacks and then optimizing the cost down.
