I've got a strong feeling that servers and hosts can be wrapped into the formula for trust, but on a case by case basis - and this may also have a manual review component if a host is flagged by the algo as looking dicey.
That could open up a whole new can of worms as servers are often re-sold or -rented. Since there's no way to check whether a domain, host or server is trusted, who knows if the next server you get has previously been abused by spammers and (manually or automatically) marked as untrustworthy.
I basically agree - authority matters much more for rankings than trust. One case where trust might be a benefit is if someone starts a Google-bowling type of campaign against your domain. Then having a high trust level may help you hold on to your rankings.
Right, it's good to keep in mind that its influence may be limited, or even variable. Nonetheless, it's probably yet another part of the puzzle that makes up an algorithm, so its existence and influence, limited as it may be, should not be ignored.
