I'm willing to pay extra for aesthetics, and I would expect a bowyer to make good on any that fail. I realize the problems bowlers have these days with clear glass, but the way for a bowyer to address those issues would be to either stop offering clear glass or to state up front that the warranty doesn't cover incidental clouding. I realize your bowyer offered to fix it, so this is certainly not intended as a slam on him, and I would take him up on his offer to refinish it, to maintain resale value, unless you plan on taking it to the grave with you.
I sometimes wonder if I'm smart to pay extra for aesthetics, because I usually drop the bow or scrape it myself in the first year or so, and there goes the "like new" appearance. For the same reason, I'm not tempted to get any kind of fancy finish work done on a new car I might buy, because I know it's just going to accumulate the normal amount of dents and scrapes as time goes by.
