There's no real benchmark for developer experience. Performance only matters up to a point. And it depends what you're building. If you're building pages where people just read content - sure - server render + vanilla js it. If you're building something more interactive where you think you'll have greater than 50k lines of JS prepare for pain.

Last note - picking the right tool for the job is a quote we repeat often in the industry, realistically though that sort of optimization actually makes it harder to reason about writing code especially in a large org. The great thing about these frameworks is that it's a single way to build and you get server and client rendering. I remember back in the day folks would ask "how do you build a page here" and it would kill me to say "it depends I have 10 questions for you"

Yep, that's my point. The abstractions are a means to an ends. And are worth their overhead in many cases. So calling them pure overhead, for sake of performance, is absurd as calling js framework as pure overhead
