The fix to A is client side filtering. That can be hard to set up if you don't enforce it to begin with. I'm currently dealing with poor/no client side validation at work and it does become a complete fucking pain dealing with poor upstream schema hygiene
I don't see why the second point is a bad thing, at all. Message buses are meant to provide a non urgent abstraction layer to simplify the relationship between producers and consumers (if you need urgency, don't use a message bus). It simplifies load balancing the consumer stage and doesn't impose any limits on producers (many of which can be clients released into the wild).
