All you have to do is be smart about your wiring.
Honestly, THAT is the problem. You can only get smart about wiring if you do it often enough. Honestly, there have been times where I gave up because I was tired of having re-place wiring while I was testing stuff out. Unless you're gung-ho about it, wiring can actually be more of a nuisance and annoyance in terms of high level usage.
If the repercussions for bad wiring aren't as tedious, players might be more willing to try wiring more and get to the point where they can get more "smart" about wiring. Though on the flip side, if the repercussions for bad wiring weren't "severe" enough, there's little point for the need of "smart" wiring.
Also, some people do care heavily about aesthetics (even if you don't see wiring most of the time.) Personally, I do prefer neat, compact wiring jobs. Of course, I've learned to balance that against practicality giving how wiring is done in the game (hence this thread). I've done electrical/electronic bread-board work (school) and I'm the one that has to make the wiring on it neat (for several reasons). Others don't care more often than do, so their boards look a bit fugly. Obviously real-life logic and practices have little bearing on game mechanics, but human habits and all that.
This is mostly a minor quibble for me. Honestly, I'd much rather have faster methods of laying down and removing large runs of wire. Compact, intricate wiring work with lots of overlap is where colored wire cutters would be a huge benefit. I generally don't do that all that often. My major issue is how much of chore it is to lay down a world-wide teleporter network, even on a small world. (The most I have is a teleporter to get down to hell. Falling down there every time I was doing a WoF farming session was taking too long after a while
