Comment(by alannisota at gmail.com):

 There was some concern on the mailing list that this patch removes support
 for the FE_GET_EXTENDED_INFO which was an initially proposed S2
 implementation back in 2006.  Since the DVB folks finally committed to an
 approach, I've posted a patch to the linux-dvb list to add support for
 S2API for the relevant cards, so I think it is reasonable to rip out
 FE_GET_EXTENDED_INFO when this eventually gets applied, however this patch
 needs to be updated to check DVB_API_VERSION and only switch to the new
 protocol if >=5 to keep backwards compatibility.  On the plus side, the
 same protocol should work for DVBS/C/T and DVBS2 cards, so it should be as
 easy as:
 VERSION>=5 use FE_GET_PROPERTY/FE_SET_PROPERTY, VERSION<5 use
 FE_SET_FRONTEND/FE_GET_FRONTEND

 On the downside, the S2API is still immature, and there is no way to query
 for DVB-S2 capabilities yet, which is annoying when trying to support a
 mixed environment.

 If no one gets to it soon, I may take a crack at cleaning up wagabunda's
 patch for backwards compatibility
