This is a huge promise. Especially with all the little "extra"s all different vendors have added. Love to read more.
One thing that separates EdgeDB from ORMs is the explicit design decision to be coupled with one specific database.
One more thing that can make me happy is to see if connection cost to EdgeDB is much lower than PostgreSql (one of the few architectural problems with PG). Connecting only (or almost only) through EdgeDB fixes this one as a side effect.
