The implicit question is what makes GraphQL and SQL different layers? They both seem to be solving the same problem allowing clients to query data with joins and projections so they can get exactly the data they want in one query. I could imagine translating GraphQL to SQL and SQL to GraphQL in a relatively straightforward way. Contrast that with attempting to translate SQL into ASM and then ASM back into SQL. This suggests to me they are at about the same level of abstraction.
