YCrCb is roughly based on the ones mentioned (which are not at all obscure from the perspective of color science), but is supposed to be as computationally cheap as possible, and so doesn't bother doing even basic steps like undoing gamma encoding.
As a result, YCrCb yields crappy results for any purpose other than image encoding. The further you get from neutral gray, the worse YCrCb gets at cleanly separating lightness from hue/chroma.
I haven’t really seen YCrCb used except anywhere for in compression, so didn’t think of including it (an neither do most papers related to perceptual color spaces).
It was used quite a bit in video editing in the early 2000s because the video frames often came from disk or a card in that format, and you could do some fast processing tricks with it. Those days have largely passed, though.
