It would be a massive mistake to conflate your personal views with the will of the majority regarding what "ultimately the benefit for D&D is." As I said, there are a number of TTRPG fantasy heartbreakers that already have your 4/8 attributes, but I can't see the Six Attributes of D&D changing in the next twenty years. Find a game that better suits your needs or make your own, but this is a line that WotC will likely not cross in the foreseeable future.Ultimately the benefit for D&D is, these eight abilities are roughly equal to each other in power and usefulness.
To balance the abilities is something many D&D players want.
