Yeah, but, after twenty years? Like I said, 5e is no different than 3e or 4e in this sense. HP haven't been a logistical resource since AD&D, and, even then, they were barely that. I cannot possibly be the only group out there that had two clerics in the party. The longest any rest ever took was a couple of days. And, again, that's ignoring the pile of potions, scrolls and various magical doodads that granted HP.That is a current I am happy to row against.
There's a very good reason why HP isn't used as a logistical resource anymore. It hasn't been one for decades.
