I'm looking at EN 302 307 figure F.1. It shows that the HP stream is a DVB-S stream of I/Q-bits (outer & inner coding, not yet spectrum shaped and modulated) according to EN 300 421, thus it cannot have a stream_id. Please explain why you think hierarchical BC mode uses MIS and stream_ids to select HP/LP. It contradicts my understanding of the standard. The frame structure of DVB-S2 is totally different than DVB-S, so a DVB-S2 demodulator will not be able to demodulate a DVB-S stream. E.g. STB0899 contains two completely seperate demodulators for DVB-S and DVB-S2 mode. Thus I think one uses DVBFE_DELSYS_DVBS vs. DVBFE_DELSYS_DVBS2 to select the HP or LP stream.
The specs also say that a DVB-S2 receiver can see both the streams, whereas the DVB-S receiver can see only the HP stream.
So the concept of using DVBFE_DELSYS_DVBS and DVBFE_DELSYS_DVBS2 for stream priority selection is definitely broken
