While on one hand I definitely stand corrected and not really floored that they decided to go against this, I don't know how marketing wouldn't have the foresight to see that a never-changing number would keep themselves evergreen. I mean, Apple still numbers the iPhone (as do other brands' flaghsips) to ensure people quickly know which one is the newest. Whereas Windows hides this designator (e.g. 21H2) behind a few clicks.
