Is there a builtin tool for removing duplicated selections from an executable?

[nrbnlulu]

e.g if I select __typename in 2 or more places in a union .
or more selection of the same field within fragments..
like so

interface Node{
   id: ID!
}

type User implements Node{
   id: ID!
   name : String
}


fragment Foo on Node{
   id
   ... on User{
    id  // duplicated
    name 
   }
}

No, there isn't. As a spec implementation, we cannot make this kind of decision; it's up to tool implementors to figure out if that's the kind of linting they'd like to provide.
