Exactly.

The maintainer process does not confer exclusive ownership, and if it
sounded like I was advocating for that, then that is not at all the
message I intended.

What I wanted to avoid was the impression that silence implied
consensus, and that caution should be taken when implying such
consensus for patches that touch multiple machines.

I want Dmitry to find *other* reviewers to look over the patch and
give cosensus over the changes.

I'm happy for Dmitry to commit them now that both you (Zack) and
Florian have looked at the patches and consider the changes OK.
Three developers is a good belt-and-suspenders peer review for
multiple-machine header changes.
