Heh.
Sometimes I think you're both right (or wrong, or there's not a difference between right and wrong in this context)...
Yeah, there's an idea (myth?) maybe even intent, that the game be played at a certain, specific pacing that could, on paper, balance hyper-versatile, high-peak-power, casters with the few benighted non-caster options, with an extra helping of complexity in the form of short rest-based classes on top of the traditional LFQW.
Is it /really/ the intent that anyone actually run adventures that grueling, though? Or is it just something to point to when someone complains that classes are radically imbalance ("they're not, your just doin' it wrong!")?
...IDK anymore....
This is why I like 13th Age. Nice gamist solution: at-will, per encounter, or per full-heal-up which happens every four encounters.
But in 5e, I'm happier and happier with rest variants to spread the time so I can throw encounters at whatever pace best fits the narrative, and have wiggle room to make it fit the resource management modules. Of course, that's with a little cheating - AiME style sanctuaries a la Elrond's Last Homely House where they can get a full rest overnight, or a magic fountain that grants a rest if I'm running a more traditional dungeon instead of a Five Room Dungeon concept.
