Hi! Just adding my 0.02$: I completely disagree with the OP. If Larian implemented this, they might just as well throw the whole ruleset out of the window. And with that, probably also the setting (licensing reasons) and therefore also the name. The game already departs from the rules in many ways, and in most cases, it is for the worse, not better - I'm of course not talking about decisions such as replacing some dice rolls (level up HP...) with their expected values, those are perfectly reasonable for CRPGS.
The "rest to regain spell slots" system works fine in both P&P and CRPGs (if properly implemented) - not that everything from P&P translates well to computer games, but this does reasonably well.
In BG3 the rest system would also work fine if time actually mattered - spells other than cantrips and once-per-*-rest abilities are supposed to be exactly that, not something you can mindlessly spam in every fight and easily regain it without consequences. If anything, resting / passage of time should have (more) consequences, or resting shouldn't be possible everywhere, or there should be random encounters when resting in dangerous places (that might just not be implemented yet) - so you are actually forced to think before using those spells/abilities. Things will get even worse with higher-level spells, as discrepancy between attacks/cantrips/per-combat abilities and higher-level per-rest spells/abilities increases.
