I think Kenny is building that team chemistry and by getting their input he is making them part of the solution. Imagine if 24 guys are sitting there thinking if they ever bring this asshole into the clubhouse again, I'm otta here (or similar) or if 24 guys are thinking, man he looked good for a couple innings, let's get behind the guy and make this work.
No matter what the scenario, Keny should know what the players, coaches, and Ozzie is are thinking before making a move. We can debate how much their input should matter, but a good GM should know the clubhouse and what is happening before making a decision.
Real world example, most companies use team interviewing for many positions. If you are applying for a marketing job you may also interview with the creative team, perhaps some of the salespeople, and the people in accounting. It is all about developing team.
