I'll keep it simpler; Before there was just one of each console, and PC for which the game(s) were developed. Now there's more variants of each console, adding additional time and resources spent on development.What does this have to do with aything? "It's the norm and all part of the development" like what does any of this mean? Are you just tossing out random arguments against the wall, hoping that it will at one point lead to a logical argument? Because it's not working.
And neither is a pro variant of a console.
How the heck is developing higher maximum settings for a high end PC hardware fine but developing the exact same settings for a higher end console a "waste of resources"? That makes no sense at all. Do you think that every PS5 and Xbox Series S/X version of cross gen games is a "waste of resources" as well?
Hopefully you understand it now. In a time with even worse expectations from stupid investors and chip shortages, a pro variant is something that's just a stupid idea.
