When all data has already been sent on a stream, we allow two responses to receiving a STOP_SENDING:
> If the STOP_SENDING frame is received on a stream that is already in the “Data Sent” state, an endpoint that wishes to cease retransmission of previously-sent STREAM frames on that stream MUST first send a RESET_STREAM frame.

The two options:
1. reliably deliver all STREAM frames
2. cease retransmission of STREAM frames, and send a RESET_STREAM instead

In case 1., it's not necessary to send a RESET_STREAM frame, since the peer will learn about the final offset of the stream from the STREAM frame with the FIN bit.
