This is discussion is like talking about photo editing before and after Photoshop. Before, all kinds of mistakes were left in pictures. Sure, there was some rudimentary (analog) fixing of mistakes, but after Photoshop, almost every photo is absolutely perfect.
Similar happened with music. With DAW, most of these kind mistakes can and are fixed. Of course, sometimes there are
exceptions.
When CD's were coming out, many orchestra recordings had creaking chairs in the quiet/silent parts, which weren't so obvious in LP versions. Since then, it's been a while since I've heard creaking chairs in classical recordings.
