I'm willing to buy this.  I'm not sure I agree, but I guess it depends
on how long until v4 is released (after all, it is just a question of
how many additional features are needed before then).  But the
dsicussion seems to have branched off toward implementing more and
more stuff into user space.  I think this would be a bad way to go at
the moment (just put this stuff into the v4 API instead).  Doing so
raises the bar substatially for dvb apps, and I wouldn't be surprised
if they just ignore DVB-S2 claiming not enough kernels support it, and
not enough people have the cards, rather than needing to change all
their code to support a user-space library (assuming I understand what
is being proposed)

Instead, why not patch in the support we need, and work on a grand
consistant plan for the v4 API, which will give user apps a clean
place to do restructuring?
