Isn't cable lacing just inferior? Let's say you need to replace a chaffed/damaged conductor. With cable ties you cut the ones around damaged area, splice in a replacement, and slap new ties on there. With cable lacing, cutting the lacing anywhere would cause the lacing of the whole cable to lose tension and unravel?

It's not too hard to slip a new wire into a laced bundle. In the places that still use lacing (aerospace), they use tefzel insulated wires that have the benefit of being super slippery against each other. This makes it easy to slip one in but it also helps reduce stiffness in the bundle because the insulation isn't sticking to itself as much as other things like vinyl.

That is why they sell wire spoons.
