Big missing con for GraphQL here — optimization. Doing the right thing in simple cases is easy; in more complex cases you’re looking at having to do custom operations based on query introspection which is an even bigger pain in the ass than using REST in the first place UNLESS all of your data is in one database OR if you’re using it as a middleman between your clients and other backend services, you have a single read-through cache like Facebook which allows you to basically act as if everything were in a single database.
