I talked to them and yes, that would be okay.
They just care about that no admin has a running root daemon by accident. Of
course we know that this is not per se a security problem but you know how
security guys are - totally paranoid :) It's part of their job.
So to quote them, "as long as dnsmasq terminates when capset() fails,
instead of falling back to root, we are happy :)"
