That's generally the reason people give for not doing the standard APIs
- there were a few architectures that didn't have DMA hardware so didn't
even have stubs for the DMA API for example, until those were added you
used to end up with build testing tripping over them constantly.  It's
much rarer to have an incompatible implementation of the same thing.

ACPI has stubs so doesn't cause issues here.

The build coverage seems useful.
