Simplicity can be a virtue, sometimes. The group in my current campaign hit 7th level recently. For most of us, leveling up took less than five minutes. The only one who took longer was the Cleric having to pick out their 4th level spells, and it was only a little while longer. And for most of the players, who are on the casual side and have less of the book memorized than anyone here on ENworld? They liked that they didn't have to spend half an hour combing through options and recalculating statistics.I also just don't think base D&D 5E has the mechanically depth to really deliver on the diversity of the 3.5 Binder. A5E, maybe.
So it's a question of priorities and trade offs. D&D 5e went with simplicity and ease of use, and the cost of that is that the design space is more limited. Classes can't get as weird or experimental. You need a more complex system with more moving parts for that. Which some games do offer, but at the cost of alienating the casual players who want something they can just pick up and play easily.
