Because smart Alek, I said I knew nothing about the rules of TT D&D. After three playtest run throughs of Early Access BG3 and testing the combat system thoroughly, I know all I need to know about the Sorcery system and how restrictive it is[...]
Just so you can clarify your point, you seem to profoundly dislike the spell slot system, which is fine, and then this is simply not the game for you. I really don't think they're going away because as other said they are a core dnd mechanic for every edition except 4e (which had more or less of a cooldown based system). But to make things clearer: sorcery points are NOT spell slots, they are an extra resource to manage, line the battlemaster's superiroty dice, or the monk's ki points, or the druid's wild shape, etc. At that point honestly i can just hope that larian won't butcher the class too much.
