In my opinion, of the alterations, pressing out a small wrinkle pales in comparison to, say, trimming.
It should be noted that there is a big difference between altering and detailing the alteration at sale, and altering and not detailing the alteration at sale. I'm not about to argue that all alteration is bad, because I don't think all alteration is bad. However, I would argue that, good or bad, alteration that will potentially effect sales price has to be disclosed at sale.
A rule of mine for selling is that if in the auction description you omit information about the item because you know the information will lower the sales price, that's something you're supposed to include in the description.
