Starting with MTL, the hardware moved to a disaggregated IP design where graphics, media, and display are supposed to be treated independently of the base platform that they're incorporated into. For driver logic that is conditional on these IPs, the code should be checking the IP versions (as read from the GMD_ID registers) rather than trying to match on a specific platform (e.g., MTL). It's possible that these IPs could show up again, without changes, on future non-MTL platforms, or that the current MTL platform could be extended to include new IP versions in future SKUs or refreshes; making sure our driver's conditions are handled appropriately future-proofs for both of these cases. Going forward, conditions like IS_METEORLAKE should be very rare in the driver; in most places our logic will be conditional upon the IP rather than the base platform.
