Not necessarily. While the detail is nice to have, not many people will focus much on it unless you purposely leave a button or two undone on the cuffs like some do. I do like them myself however, and a couple of times when I've worn my suit out I've found them useful for washing my hands. I think the most attractive thing about it, as has probably been said here before, is a. the suit has that kind of detail put into it and b. the affection for many sartorialists about having a lot of handwork on suits. (One reason kitonbrioni previously said he likes an off the rack Brioni rather than a Savile Row bespoke item, though the amount of handwork in either compared to each other seems up to debate.*) In answer to ......2's question, I think you should only trust someone you've known to do this well on others' jackets before. The main thing to ask yourself is: With how much (or little) I paid for this, is it a good idea to trust him?
If it's an inexpensive suit, I would leave it alone personally. *If this isn't you, I apologize, I'm just going by memory.
