Hello,

my apologies if this question has been addressed before, but why do we
need request types in parallel to the request class hierarchy? Could you
perhaps describe one scenario in which the class hierarchy alone would
not be sufficient? Or was the decision driven by performance advantages
(?) of equals() compared to instanceof?

That's one reason. Another is to avoid the creation of unnecessary classes.
