Personal oppinion, but its already very easy as it is. You see that perception is rolled and you can simply give guidance to your second character. Resetting it on rest is barely more a nusiance than reloading a save - so from my perspective it doesn't solve much except for those who want to say they don't save scum, while just repeating all tests with 4 attempts after each rest. I'd guess you can anyhow have a new set of companions run through the area as well.
I wouldn't mind if they do it like in Pathfinder WotR where you get a new attempt after each level up.
My thoughts were that, resting costs supplies. so its limited even there, though i know this game throws supplies at you, but it's still a theoretical limit while loading and saving doesnt.
also for pathfinder are you sure its every level or every rest? I remember in kingmaker I used to setup a camp somewhere and try to get some check solved. everytime i failed i rested and tried again.
