My point there is that there's nothing obvious in the mail that suggests
it should get past filters - just being CCed on a mail isn't super
reliable, people often get pulled in due to things like checkpatch or
someone copying a CC list from an earlier patch series where there were
things were relevant.

Why would we want to do that?  We'd continue to support only DT systems,
just with code that's less obviously DT only and would need to put
checks in.  I'm not seeing an upside here.
