Thunderbolt still doesn't provide the full PCIe bandwidth, but even if it did, I'd want PCIe itself. I don't trust the encapsulated version over Thunderbolt to work the same.
Virtualized Linux would be ok though. That's what datacenters already do with their GPUs, albeit on x86 not ARM. Doesn't need to be Asahi, cause that's unlikely to completely work.
