> +The final size of a stream is always signaled to the recipient.  The final size
+is the sum of the Offset and Length fields of a STREAM frame with a FIN flag,
+noting that these fields might be implicit.  Alternatively, the Final Size field
+of a RESET_STREAM frame carries this value.  This ensures that all ways that a
+stream can be closed result in the number of bytes on the stream being reliably

The implicit refers to the Length field, which is implicit when omitted.  Some tweaking might be required for that.
