The n+1 problem is real but I do think dataloader is a very ergonomic solution. In a simple REST API using your ORM's preload functionality is even more ergonomic, but in more complex cases I've seen a lot of gnarly stuff like bulk-loading a bunch of data and then threading it down through many layers of function calls which definitely feels worse than the batched calls you make to avoid N+1's in gql.
