The browser is only half (the client-facing side) of the equation.

GraphQL endpoints are introspectable.

A model with unrestricted introspectability wouldn't have worked as a web-replacement anyway, it is not secure enough!

There are even servers like Servant for Haskell that make REST a first-class citizen of the server programming language. So we have the best of both worlds now: security and convenience.

The browser? Oh, you mean the WebAssembly Virtual Machine?

Can we point to the S-expression syntax for Wasm and say we've come full circle? :)
