The features in question are platform agnostic. They could temporarily disable the detouring for native ARM64 apps since the mechanism is broken on that architecture, but it's not ideal since the Snapdragon X platform is one of the main platforms for the Auto Super Resolution feature. Upgrading sequential/blit mode swap chains to flip model theoretically should be legacy, but as OP shows, it's not really as new graphics code is still being shipped without flip model support.

Note that the detouring problem is only an issue for native ARM64 programs. x64 programs running in emulation on Windows ARM64 work fine.
