Nah, I'm in the same boat and it's probably the only reason I haven't purchased a SM300 MC yet. I don't mind small amounts of polishing, but the large bands of polished and brushed surfaces alternating (like the SM300 MC, modern Daytonas and GMTs) really aren't to my aesthetic liking.
Getting it brushed afterwards is always an option, but polishing the bracelet back to original condition in case the watch needs to be sold would present a problem since there's only so much steel material to work with on bracelet links.
That being said, I think the new 57 like the OP's would look incredible if the bracelet was all brushed. As it presently stands it's a very striking piece, but the stainless steel bezel works better with fully brushed surfaces on the bracelet IMO.
