BG allowing the players to rest “as much as they liked” with hardly any drawbacks was one of the shittiest things about the game
And it was. It was a resource management mechanic, without any actual management, as resources can be reaquired at almost any time, any amount of times, making the whole system pointless. I don't see what random encounters are to add to this outside flavor, not in this "structure" - if you need to rest, you will rest regardless and reload if ambush is too much. If you don't need to rest, then you likely can defeat ambush and rest anyway.
Similarly to camps supplies in PoE1, current food system, at least encourages more efficient play, while still in theory providing nearly infinite supply of long rests, unless food economy becomes far tighter in 1.0. Not terrible.
I would be shocked if the camp won't be used for a combat encounter or two, but I expect them to be more of scripted events (ala. Dragon Age: Origins) then regular systemic ambushes - it is after all less of a campsite and more of a home base. It looses the home-feel if it's raided by uninvated guests on a regular basis. So more of a pocket dimention from Throne of Bhaal, then resting in BG1 or 2.
EDIT:
If you dislike any sort of chese, then don't use it. Play it single-player and *you* make the rules.
But that assumes I already know the game in and out. I don't want to have to invest significant amount of time into a game, to then be able to have a good experience. If it is about difficulty, then we have difficulty options for this very purpose. A modular difficulty settings (like Pathfinder) are even better!
A good system should encourage fun play. If devs don't find resource management fun, they should remove it (aka. Pillars of Eternity2). And if they do, they need to create coherent rules around it. By the same logic you could give players infinite healing potions, and gold, and then ask for them to decide how much of it they want to have fun.
