I'm sure it is deliberate. WotC has a history of overreaction. They see something not working, so they go too far in the other direction. Bounded accuracy was good, but they over bounded it. 3e was too unbalanced and feats too swingy, so they over tightened the math and made feats virtually meaningless in 4e. 3e and 4e put out too many products, so they overreacted with the 5e release rate.
But the good thing is that they can always increase the release rate; it is harder to dial it back once people get used to a certain amount. Honestly, it sounds like you simply want more product. I want plenty of things--Earthsea and Malazan setting books, for instance, or deluxe legacy setting box sets once a year--but don't necessarily conflate that with what would be good for the company.
As for the rules stuff, I actually agree with some of it. Bounded Accuracy to +7 or +8 seems about right to me. Feats vary. I don't like hitching them to ability score increases. I'd rather have them be a separate addition every 4 levels or so.
