To reply to myself, I think I came across as being too pessimistic.
Let me summarize this way:
Most linux developers care about:
- Recording TV as a progressive stream at low resolution
- Watching TV in a window at frame-rate not field-rate
- Using capture cards for webcams
Some Linux developers care about these 'high quality' things:
- timecode [1]
- 59.94/50hz TV watching [2]
- full-height/rate recording from consumer cards such as bt878 [3]
- inversing telecine [4]
- NLEs that can do nice compositing etc [5]
- field correct TV output [6]
Most Linux developers don't care about:
- support for hardware we can't afford (digimix, etc)
- targeting professional studio markets (we're mostly all users)
Sound reasonable?
[1] Timecode decoding is in my V4L recorder:

[2] Check out my deinterlacer, others apps also sorta doing full-seed
output:

[3] I know my recorder intends to do this, I'm sure others do.
[4] There is now lots of 3:2 pulldown inversion code in the linux
scene, see my recorder for an off-line algorithm, mjpegtools has
another, etc.
[5] Check out: http://matterial.sf.net/ for one project, there are lots of
other little NLE projects, mostly people with DV cams though.
[6] I keep meaning to do this more. The V4L2 API at least gives us the
start of something we can write drivers for.
