The gap it fixes

Born from real evidence in JetBrains's own official GraphQL plugin (millions of downloads), not assumptions:

"Basically does not work in projects with multiple schemas. The documentation for setting up scopes is terrible and it straight up does not work at all." — multi-schema/multi-endpoint support has been an open, unresolved request since 2016.
Performance degrades to roughly 1 character per 1.2-1.4 seconds, with no syntax highlighting at all, on large (3000+ line) .graphqls files.
A recent regression: schema discovery reported broken after upgrading to a newer IDE version.
