Could also be because of the Arm chips which add more burden on the developers who have to account not only for another OS but also for a completely different CPU instruction set.
This is probably not as big of a deal as the lack of common APIs like Vulcan. I doubt Valve has much (if any) raw x86 code in their game engine, and it would probably compile to arm just fine. You still have to set up a new build chain for this, though, which is a pain.
