Thanks, CXL.io is outside of TSP. CXL.io IDE is a nearly identical programming model to PCIe IDE (some edge constraints are different). So unless and until there is a solid use case to cause the kernel to consider PCIe Link Stream IDE, then CXL.io IDE can also live in a "Selective IDE Stream only, for now" world.
