Supporting interop with any device is always possible. It depends on which drivers we need to interoperate with and update them. We've already found the path forward for amdgpu. We just need to find out how many other drivers need to be updated and evaluate the cost/benefit aspect.

Since I think you mentioned you'd only be enabling this on newer
chipsets, won't it be a problem for A+A where one A is a generation
behind the other?
I'm not really liking where this is going btw, seems like a ill
thought out concept, if AMD is really going down the road of designing
hw that is currently Linux incompatible, you are going to have to
accept a big part of the burden in bringing this support in to more
than just amd drivers for upcoming generations of gpu.
