def perform(supergraph, composer)
  # @todo
  # Validate all supergraph interface fields
  # match possible types in all locations...
  # - Traverse supergraph types (supergraph.types)
  # - For each interface (.kind.interface?), get possible types (Util.get_possible_types)
  # - For each possible type, traverse type candidates (composer.subschema_types_by_name_and_location)
  # - For each type candidate, compare interface fields to type candidate fields
  # - For each type candidate field that matches an interface field...
  #   - Named types must match
  #   - List structures must match
  #   - Nullabilities must be >= interface field
  # - It's OKAY if a type candidate does not implement the full interface
