For those who want to be challenged, tracking the total number of long rests taken, and somehow factoring that into the game later on, such as having certain events/items/vendors later in the game disappear after X days, would be an added incentive to play efficiently.
So ...
In order for you to "be challenged" the way you wish to ... system must change so everyone else will "be challenged" the way YOU wish to ... no matter what they wish to? :-/
Im unable to understand this mindset. :-/

Yes. The answer is "Yes."
You know, ya can't make everyone happy or you'll never finish the game. I think they should absolutely make the game the way I want them to make it, you know, in a way that is based on D&D 5e, like any Faerun game should be made, with D&D 5e stats and xP rewards and so on and so forth.
You know, like they used to. Did they ever used to ask? No. They just made the game, and if you didn't like it... Tough.
And like they used to, if some people are a bit unhappy about the game design, they either put up with it or didn't play it.
And in reverse, if they're gonna NOT make it D&D 5e, then just own it, do it and let's move on. You know, like Neverwinter online. They don't follow 5e rules, but it's an MMO. People accept it and they either enjoy it or they don't play it.
I say, enough of this, "Let's create an option in the endless difficulty options menu we keep asking them to make that they don't really seem to be making.
So yes. Absolutely. They should make the game challenging the way I wish them to because that's what I want. If you don't like it... Tough. :P
I say, everyone suggest what you want and hopefully the majority will want what I want. Power to the majority!
As long as the majority wants what I want. 😏
