Assume defaults:

Schema A: 1
Schema B: 2
Schema C: 3 (external)

Wouldn't this compare:

3 with 1
3 with 2
3 with 3 (redundant)

i.e. External defaults shouldn't be included in defaultValues?

does this change the outcome of the rule?

I more or less try to word the rules as simple as possible.

The actualy implementation of the rule would be completely different anyway i believe.

Hmm. I'm not sure. Maybe not in this specific case.

If there were more than 1 external argument, it would fail if the default values of 2 or more external arguments didn't match?

Assume defaults:

Schema A: 2
Schema B: 2 (external)
Schema C: 3 (external)

Compares:

2 with 2 (B - A)
2 with 2 (B - B)
2 with 3 (B - C [external - external])

3 with 2 (C - A)
3 with 2 (C - B [external - external])
3 with 3 (C - C)

Also the explanatory text is:

This rule ensures that arguments on fields marked as @external have default
values compatible with the corresponding arguments on fields from other source
schemas where the field is defined (non-@external)

🤷‍♂️
