(Edit: Yes, I'm aware a lot of people care about FP, "Clean Code", etc., but these are all red herrings that don't actually have anything to do with quality. At best they are guidelines for less experienced programmers and at worst a massive waste of time if you use more than one or two suggestions from their collection of ideas.)
Most of the industry couldn't use objective metrics for code quality and the quality of the artifacts they produce without also abandoning their entire software stack because of the results. They're using the only metric they've ever cared about; time-to-ship. The results are just a sped up version of what we've had now for more than two decades: Software is getting slower, buggier and less usable.
If you don't have a good regulating function for what represents real quality you can't really expect systems that just pump out code to actually iterate very well on anything. There are very few forcing functions to use to produce high quality results though iteration.
