this is the direction i've been wanting Netlify to go in for years! Netlify has done very well as an aggregator of frontend developers, and GraphQL is the perfect protocol to 1) build better tooling, which onegraph has a lot of ideas on, 2) commoditize their complements (https://www.joelonsoftware.com/2002/06/12/strategy-letter-v/).
i hope more updates keep coming (i want explorer in the UI! not the CLI!) but this is a positive start.
