One justification is that you can't ever have two contexts of the same
type next to each other as siblings (and recall that generic types are
never kept at runtime so you can't include them in expressions indicating
a class type either).

We could have done separate context types, InboundMessageContext and
OutboundMessageContext, but we haven't done that much (subclassing context
types to give them different semantics).
