As a GM, I’ve occasionally said things like “It’s clear that this combat isn’t that interesting, and that you are going to win it. Are you interested in playing it out, or should we go around the table and you each tell me one cool way you kill a skeleton?”. I would consider a suggestion like that from the players. But, you know, that was in a pathfinder adventure path with some dumb filler encounters that the designer didn’t think through, so I think it just shows that the source material has similar problems.
