Yes, this is entirely a political issue and not a technical one.
Every couple of years somebody implements such a driver, and they have
all been rejected for upstream.

The unfortunate fact is that allowing this sort of thing *does* allow
for abuse of the interface, even if was not the intention of the
original author of the patch/driver.  In fact, I believe all the cases
in the past were by people who were friendly to open source.

To be fair, I am not the originator of this argument.  If you read the
history, a variety of other Linux DVB-V4L developers have shared the
same view (which I adopted after hearing the arguments).
