They simply don't want cache coherent peripherals (except perhaps occasionally when entirely owned by Intel). Their hand was forced by AMD, ARM, IBM, Nvidia, etc. threatening to develop their own standards.

CXL was entirely about having more control of the standard. They don't want it, but even less do they want competition to create an ecosystem around a standard they might have to eventually adopt.

Exact same scenario happened with amd64 except that time AMD kept it secret long enough that Intel wasn't able to change Microsoft course. A big black eye for them and something they are terrified of. Hence CXL.
