I was just watching Rick Beato's interview with Billy Corgan and one of the things they dwelled on was that while the early band had intonation and feel sorted out, they were a mess with keeping time (i.e. "playing to a tick") and it caused a number of interesting problems for them as their popularity exploded and the production level of their albums increases. They all eventually had to learn to play correctly because it enabled them to bring in other musicians, and layer in other sounds more reliably. It also more or less became a requirement in the post "pro-tools" world that they transitioned into.
