This ticket has been moved to https://apollographql.atlassian.net/browse/FED-76.

Instead of attempting to reuse user provided fragments which requires complex rebasing logic we should look into an alternative of auto-generating the fragments.

See apollographql/federation#2892 for details.

this can be even contributed to graphql-js, graphql-java, any spec implementation.
not related to federation at all, it applies to any syntactically valid AST no need for an schema.
