That nuance is already possible: if the application wants to hand the transport this power, it can.  It can provide a default code for the entire connection; or more complex expressions of policy can be made (e.g., even streams get code X, stream Y gets code Z, otherwise don't touch).  That is a negotiation that can be managed at the interface between application and transport code.  Without that information, the transport is always able to access the final solution.

As for the suggestion that an application can ask the transport to use one of its own error codes with CONNECTION_CLOSE (0x1c/transport), that's another negotiation for the API they share.
