If you're comparing JSON:API to GraphQL then yes, there are some more decisions to be made, like filtering and sorting. (Includes are well specified in the spec- what bikeshedding were you doing?) But compared to not following a standard, you were going to have to make those decisions anyway.

This doesn't seem right to me. What issues were you having trying to specify a JSON:API service using OpenAPI?
