I'm not aware of any claim that they intend to rework the rest system, frankly.
There is a thread(this one
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=817694#Post817694) about reworking rest system with keeping camp supplies(basically remove 2 per day restriction and make SR cost camp supplies as well as make LR more expensive overall to differentiate SR and LR more).
Larian asked our feedback on camp supplies system, so I hope they are watching and maybe do something like that
