Suggestion

I'm playing with ESQuery type inference and I just noticed that there is a selector that queries a node that cannot be represented by the current AST structure:

Little context:

1. Why it was added:
   Issue: [no-unused-var] False positive for nested namespace declaration #2573
   Fix: fix(eslint-plugin): [no-unused-vars] don't report nested module declaration #3119
2. Why it's not needed anymore:
   fix(typescript-estree): account for namespace nesting in AST conversion #6272

If I entirely remove this listener, all tests still pass, so it's dead code
