data creation via the reverse edges?

[hartig]

As per #19 (comment), @keski asks the following:

The purpose of the reverse links is primarily to make querying more flexible and expressive. However, do we also want to support data creation via these reverse edges? For example,

type A {
   value: B
}

type B {
   name: String!
   _valueOfA: [A] # Reverse link, 1:N
}

input _InputToCreateA {
   value: _InputToConnectB
}

input _InputToConnectA {
   connect: ID!
   create: _InputToCreateA
}

input _InputToCreateB {
    name: String!
    _valueOfA: _InputToConnectA # do we include this field?
}

input _InputToConnectB {
   connect: ID!
   create: _InputToCreateB
}
