YUV is known as components. I dunno why it appeared on domestic
equipment as it was originally a way of recording high quality
pictures to professional videotape. And really offers no advantage in
theory over RGB via a SCART.

Component will also often be the only connection available that will
support progressive scan on a fair bit of kit - so is handy for
projector use.

I know that - but there's no reason RGB couldn't support progressive scan.
