You know what nobody talks about? How this messes with future work. Say you want to add a window later, but the framing's all cut up from wires. Or when the next owner tries to hang a heavy TV and the stud finder fails because of all the notches. It's not just about keeping the job moving today, it's about avoiding big problems for years. I've seen homes where shortcuts like that meant whole walls had to be fixed just to run new lines. Speaking up might slow things now, but it saves a lot of trouble later.
