Any co-called "1.3" cable would quite happily work with 3D and 4K just as well as a so-called "1.4" cable as they would both actually just be High Speed cables.

With some of my HDMI cables CEC would not work between some devices until I replaced them with newer ones, so assumed it was the same for ARC which was supported from V1.4. It makes sense for the interface to be the one that supports it like you say, but experience of the actual cables has shown that not all cables are the same. Pretty sure the ARC is a dedicated wire on the cable too, which only got introduced later in the spec.
As for the higher bandwidth of HDMI v2, is that all done at the interface too or do you need a certain quality of cable to ensure it works? It's entirely possible for a cheap cable to have problems with 1080p while not having problems with 1080i although I am not sure of the reason for this. 4k tv would need at least 4 times the bandwidth of a normal stream and I guess it would depend on the quality of materials used in the cable as to if it would struggle or not?
I'm not one for buying expensive HDMI cables as digital signal is the same from end to end so buying a £20+ cable is pointless. The really cheaply made ones can have problems with the signal but it's more likely to have a fault along the cable as it gets moved or have problems with the connection plug as it ages.
I assumed the ones sold as HDMI v1.4 or 2 have been tested or certified to work at that speed, compared to another one that is sold as v1.1. Going by what you have said there is nothing stopping someone who has been selling a HDMI 1.1 for donkeys years could change the description of it to be a HDMI 2 cable.
