Take into account that she's focusing on the 3D stack, not the overall hardware. Even with hardware differences there's a good chance it's not different enough to make it an interesting new challenge.
Yes I meant the GPU specifically not the hardware in general. An example is the support for hardware ray tracing in M3 and beyond. In some now deleted french fediverse post Alyssa indicated M3 has a new architecture.
Given the features that have been advertised for the M3+ graphics and compute stack, there's rather a good chance that it is different enough to create big, new challenges for third-party support.
