I am not super happy about it being an Oculus exclusive. Yes we can run revive and get the game to work but there were performance issues with Dirt Rally with that approach that made it pretty problematic. There isn't a lot of excuse to be limiting yourself to the minor player in the VR market these days especially with all the generation 2 devices out on SteamVR right now.
There will eventually be a thinning of the herd and standards. For the next few years there will be lots of confusion that will divide development efforts. This is one reason I wasn't thrilled when WMR came out. It was yet another set of specifications even though it is a standard.
As it is there is the whole RTX debacle. It "could" make a game dev's live easier "if" they didn't have to continue to support everyone who doesn't have RTX ie. 99% of the gamers out there.
In the end we need a common specification for everyone, but somehow we need to make progress.
It's a tough balancing act and you will never make everyone happy.
