But, that isn't what people want from the game.
There's consensus on what "people" - all seven billion of them - want from the game?
Whether by "the game" you mean 5E, or all the editions through 5E, I disagree. Many people have wanted many different things from D&D. Many of them have achieved the things they wanted, often by creating variations, such as Spelljammer. Others created separate games, such as Empire of the Petal Throne, or Tunnels and Trolls.
There are things I want from TRPG, and things I want from D&D, and things I want from 5E. If what I want, isn't what you say people want from the game... does that mean I'm not in the category of "people"?
(shrug) This is a bigger question than the OP. I'm happy that the Blessing is available, in a WotC publication, for those who choose to use and include it. Meanwhlle, I'm free to pursue different and divergent things, using as much of the 5E chassis as suits me and my goals. If I want Vancian magic, or if I want Hogwarts style magic, then I'll change the interaction of spell preparation and spell slots; I'm okay with that.
My point was that 5E is not nearly so setting-neutral as a dictionary, nor as Fantasy Hero, nor many other books. (If you don't want to consider books by publishers other than WotC, then leave the dictionary out of this thread, eh?)
