garbage? no
suboptimal? i guess? but the hyperoptimization mindset for exercise is stupid, there's a general range of effectiveness for movements and programming and anything that falls within it can work for some better than others, if you enjoy deadlifting its a movement where you get to move big weights, which helps build mental and physical endurance, which in turn allows you to push yourself harder in other sets now that you know what an actual hard rep feels life
on the other hand if they hurt or you simply dont like them there's plenty to replace them with, but you are not gonna stay small or blow up just because of 1 exercise
