I hear you, but how often have you had to swap out a cable compared to how often have you had to deal with a rats nest? This isn't a whole lot different than zip tying groups of cables together.
IMHO this would be even better with 6 different colors per braid. Then you could trace a cable in a few seconds while also not having a rats nest.
Edit: oops, this was supposed to be a reply to another comment.
