Too fancy why?

Again my point about waste.

I think we could find the minimum common ground from a variety of query languages (sql, nosql, graphql), primitives that have emerged for most use cases. I'm not advocating for anything too sophisticated 

The relay I wrote runs SQLite on Bun.js, it's crazy fast to the point that calls are non-blocking and all that on a $20 VPS.

If slight more complexity makes it bad for huge relays, then that's also a good thing
