I don't think it's necessarily a trust issue, but is an availability
issue: one of the reasons shared maintainership models exist is so
that one maintainer can go on vacation (or focus other work) while the
other maintainer(s) take over. If we send a review request to that
maintainer he might be away and we'll never get our review.
