I was immediately thinking of inertia.js.

Inertia is "dumb" in that a component can't request data, but must rely on that the API knows which data it needs.

RSC is "smarter", but also to it's detriment in my opinion. I have yet to see a "clean" Next project using RSC. Developers end up confused about which components should be what (and that some can be both), and "use client" becomes a crutch of sorts, making the projects messy.

Ultimately I think most projects would be better off with Inertia's (BFF) model, because of its simplicity.
