You continue to just say it depends without giving any actual scenarios. You make it sound like magic, but it’s not: “under x and y, do z except when u” is better than “it depends, I’m sick of all these noobs”.
Also, your main points are against denormalization and avoiding large table joins which are 100% rational arguments under certain workloads.
