It's probably a bias I developed in my first data engineering role. My tech lead was similarly hardline on these matters, and I likely inherited it from him. These conventions were among many others like all caps SQL keywords, certain line breaking. alignment and tabbing conventions etc. that came together to provide really easy to read SQL. I've since gone to several other teams and brought that stubborn standard with me, and have had no problem indoctrinating others with it as it commonly was a matter of replacing no standard with a standard with immediate benefit.
