Since CXL uses the PCIE 5.0 physical link then it is a good bet it will becomes the defacto standard of all next gen compute interconnect links. Especially since it is already seeing adoption on Intel's FPGA platform. CCIX is still using PCIE4 links so it is "behind the times". While it may seem like a simple "lets just upgrade it to 5.0 spec" type thing, the hardware layer is very similar between the standards, 5.0 is mostly just a drastic change in signal encoding. So CCIX would have to undergo this major signalling change in order to jump up to the higher standard while CXL is already there.
