Oh. My. God.
This is precisely and exactly what I've been arguing as a flaw in 5e's design since before it was even CALLED 5e.
Twelve years now, I've been told I'm crazy. Hateful. Biased. "White room"ing. Etc., etc., ad nauseam.
Now it's literally coming straight from the horse's mouth. Will folks retract any of that? Hell no!
Well, it is kind of a white room thing. The designers assumed more exploring, and more pressure by the GM. But the typical playstyle turned out to be tactical puzzle-solving. The DMG has given (fairly accurate) estimates of what encounters will make the game run as attended. And many, if not most, GMs just ignored that part.
