Possible bug in GraphQL layer in Dgraph when altering schema via /alter

[Anurag]

One should not try to modify schema through /alter if they are specifying schema through GraphQL. If one is using only DQL, then only they should use /alter . If they are using GraphQL, then they should use only the /admin/schema endpoint to modify the schema. Both of these endpoints together are not supposed to be used because they serve different purposes.

Does GraphQL provide support for deleting the unused predicates and types? Slash has this usecase because they modify the schema via /admin but that doesn’t remove unused types and fields, for which they use /alter.

But, I am not entirely sure if there is a reason behind this behavior in the first place.
