We're all very driver-development-driven, and userspace gets very little
attention in general. So before just throwing in the towel we should take
a good look at the reasons why there has been little or no development: is
it because of fundamental design defects, or because nobody paid attention
to it?

I strongly suspect it is the latter.

In addition, I suspect end-users of these complex devices don't really care
about a plugin: they want full control and won't typically use generic
applications. If they would need support for that, we'd have seen much more
interest. The main reason for having a plugin is to simplify testing and
if this is going to be used on cheap hobbyist devkits.

I think you're looking at it with a programmers hat on, not a users hat.

Are you really telling me that requiring users to 'su' to root, and then
use media-ctl to manually configure the capture device is what most
users "want" ?

If you want to help users, right way is to improve userland support. 

Hasn't the way technology has moved towards graphical interfaces,
particularly smart phones, taught us that the vast majority of users
want is intuitive, easy to use interfaces, and not the command line
with reams of documentation?

How is it relevant to _kernel_ interfaces?
