Just ask yourself:
- Who are the people who wrote the DVB-S2 spec?
- Why did they write it the way it is?
- Which parts of it are relevant for whom?
- What are your goals for the Linux DVB API?
- What is the price to pay for achieving this goal?
If your goal is to support every wrinkle of the DVB-S2 spec
just for the theorectical case that someone could need it sometime,
then your goal is different from mine.
If someone can explain to me how advanced features of
DVB-S2 are useful *today*, and how an application
would work that makes use of these features, I'm
all ears. Otherwise my advice is: KISS.
