I'm very concerned about this statement.

Yes, it would be nice if all HW was sanely designed, but it's not
always. The time to push back on bad HW design is during IP licensing
agreements or HW design reviews, not upstreaming.

Any pushback during SW upstreaming simply serves to make it difficult
for the SW people doing the upstreaming. It has zero impact on the
current HW design (it's already shipped). It probably has zero impact on
the next N revisions of the HW (they're already baked). It's possible it
has zero-to-minimal impact on any future HW (end-user product
requirements are what matter most).
