This has been a longstanding ergonomic issue with our IPC compiler. Non- trivial types were previously passed by const&. So if we wanted to avoid expensive copies, we would have to const_cast and move the data. We now pass ownership of all transferred data to the client subclasses. This allows us to remove const_cast from these methods, and allows us to avoid some trivial expensive copies that we didn't bother to const_cast.
