you can use the same input prefilter functions for the compositor, where 
is the problem?

Maybe that is a misunderstanding:
we don't try to replace the effect stack of the sequencer here!

The filter stack within the sequencer does *pre*-filtering!
And that should be done correctly! (YUV -> RGB is a lossy operation)

Please don't try to "generalize" things here in the notion "RGB is good 
enough for everyone", since that actually doesn't solve the problem.

There should be a path for RGB input, too, but we shouldn't limit it to 
RGB input...
