Yes, both them and their devs have announced support for foveated rendering.

It really does suck that PC VR keeps lagging behind.

The only issue with the belief that "oh well it's not like we can make use of it anyway" is that in reality, fixed foveated rendering already gives us a huge performance boost (the Unity devs with PSVR 2 quote 2.5x, while dynamic foveated rendering is "only" 3.6x). So we could have that performance boost already since 2016, if the industry just cared to do it.

The video cards also need to support it and I'm not sure Nvidia can apply VRSS+VRS to everything. Apparently VRS doesn't even work in games with deferred rendering. And even then, it needs to be implemented by devs. Meanwhile on Quest today, you can apply it to any app just by using debug tools.

Unfortunately OpenXR's only an API, you still need support from GPU vendors. And on PC, AMD doesn't have any support for FR. Nvidia does but only through VRS/VRSS which has limitations. And then there is Varjo's OpenXR extension which does quad view rendering and has its own set of trade-offs.
