different tool for different aspect.

using OPENAPI, rpc, GQL types in client, etc to share typing (schema) information between client/server

resolver/dataloader in GQL, eager join in ORM is to handler internal data composition

presenter layer should not care about data composition, so that writing Query at presenter is an anti-pattern.

presenter should fetch schema info & data passively, like what https://github.com/hey-api/openapi-ts did, the job of implementation belongs to backend.

In fact what rest/rpc really need is the resolver and dataloader, to help backend easily extend or composing data together, and immediately transferring the schema & data to clients.

pydantic-resolve is the python binding for this idea.
