I hope this isn't off topic, but for those of us still using SD formats,
we need YUV and not RGB. I tried RGBA for a while, but I always got
artifacts, so I went back to YUV. No artifacts.

No. :-)
With your proposed studio swing
mapping most compositing and filtering operations have to scale
and bias to work right. E.g. black + black + black will be a
shade of gray, unless a bias is subtracted.
Yup. I was suggesting it as something of a path of least resistance.
For the record, we already have this problem with studio swing.
How much is a lot? One conversion entering the pipeline, and another
exiting the pipeline?
Any color filters that expect to operate on R'G'B' rather than RGB. I
think in most cases, these operations only work on R'G'B' to avoid the
additional conversion, but there are probably at least a few that
really do want the gamma space. They'd have to convert.
The dilemmas just won't end, will they? :-/
If it was easy, it would be done already :-)
