Gameplay first, graphics later. We are already on one of the most advanced engines with a solid graphical engine, we don’t need to push it any further yet so I don’t see any of this new technology being part of our game.
You’re right, it wouldn’t make sense to remove a feature solely because it doesn’t work on everyone’s machine.
But the point I’m trying to make here is that as game developers, we want to spend our time working on features that everyone can enjoy, and avoid / postpone features that only people with specific hardware can enjoy.
There are cases where we’ll make an exception based on what the feature does for our game. But generally, this statement holds.
