Other than the camera implementation, GPU is the only subsystem with >10.14 SDK requirements:

Probably just have to assume unsupported on these SDKs...

[flibitijibibo]

This should be tested against an 11.x SDK, if it compiles there this can be closed.

[flibitijibibo]

Forgot to write here that 3.0 is indeed getting an SDK bump, ideally to 11.0 but may end up being 11.3 based on what Sam suggested.
