airbnb and graphql had the problem to have scalable APIs that can grow, are flexible and are backward compatible graphQL solves this problem, so lets say we have something like this:
persons { id firstName lastName email pets { id name }}
persons { id firstName lastName email pets { id name }}
now I can grow add other relations to my persons, without breaking my code, so persons can have addresses, bank accounts, children, cars, bought products
how does tRPC grow that way how does tRPC is telling you how to have flexible interface?
