I agree with all your points. I think the obsession with completely perfect vocal performance has gone too far for my personal taste. Modern mainstream pop records have a combination of too many takes spliced together for one "perfect" take, together with minor correction of the odd note here and there and the end-to-end result is "too perfect" for my old ears. There's no mistakes or personality in many of these records and it sounds boring to me. That's all. I'm not claiming to have the only valid opinion on the matter, or that all modern music is like that, and I also know I'm also not alone in my thinking and taste.
