I totally "get" the value of a dork-disk, especially when the frame, derailer or a re-spoking job for the wheel are very expensive.
But I stopped even considering using them myself after noticing that modern chains allowed me to set the lo-limit screw tighter, while still getting a crisp shift up to the largest cog.
My last three chain-in-spokes incidents were due to 1) a pulley bolt that loosened, 2) a derailer cage pivot shaft that ejected on it's own, and 3) a Simplex derailer that had the lo-limit screw boss break off.
So not to say that a dork-disk has no value, it does.
I have a dork-disk on one bike, and I don't think it looks at all tacky. I wouldn't even consider removing it!
I did have to repeatedly loosen the freewheel 3-4 times and rotate this heavy steel dork-disk to different positions on the wheel in order to get the freewheel cogs to run straight.
Also, the disk contacts the spokes and there is a continuous noise from the spokes rubbing ever so slightly against the dork-disk. I had to put a spot of elastic glue at each of the nine contact points.
