Oh, sorry, I thought this was in the sub thread about “why not mark cables in software”!

Fully agreed – the maximum supported data rate would be even more important to be printed on the cable for HDMI.

One reason I could see why manufacturers would be hesitant to do this is that some future improvements might not have higher requirements for cabling, so the printed data rate might be underselling actual capabilities.

As a consumer I'd much rather have a cable rated for one level and end up actually supporting more than not having any information at all.
