I don't understand this perspective. I've developed, delivered and maintained countless Next.js projects and never come close to considering it "high cognitive overhead." It's among the nicest DX I've experienced. It has a lot of features, I guess, but you don't have to use them if you don't like them. Next.js has very little to do with the frontend. The frontend is literally just react, which is why I commented in the first place. People keep acting like it's a "frontend framework" which doesn't make any sense at all.
