The only reason to care about the exclusion is that you want to be in the default trust network and have your own feedback show up for everyone else by default. The other effects you seem to be upset about are non-existent.
You summed it up here. the feedback which would have been visible to those in the default trust is not not visible, effectively lowering my visible trust rating for the VAST MAJORITY of the users here. So no, it really does exist because I earned those trust ratings, now suddenly they are effectively negated, but of course "trust is not moderated".
You are a liar - therefore not trustworthy. Your ratings should NOT show up in the trusted feedback, because there is a good chance they are lies.
