And if not clear GraphQL is not "SQL on the web", so just because your DB schema changes, your GraphQL API doesn't have to change (basically like REST)
I'd argue all these "publish your DB schema as a GraphQL endpoint" frameworks that seem to proliferate have done a lot of damage to GraphQL's reputation. Strongly coupling data to presentation seems like such an obvious anti pattern, yet tools doing just that seem to be very popular for some reason.
Agreed, the reason I really like GraphQL is you can map different parts of your schema "tree" to different backend systems, APIs, etc. This makes your API plane/BFF nicely decoupled from those details like DB tables, etc.
