Validate choice of `PathToExport` name in ES Modules

[andreaphylum]

In this bit, the ESM PathToExport is named default only if a condition is satisfied (the default export scope should be the same scope of the last accessed node).

Is this expected behavior? This form of export would, regardless, expose a symbol of default to be imported by dependents. Is the name field used only for display purposes, and thus it would make more sense to represent this as an identifier rather than default?

We should investigate this and build unit tests to validate our intentions.
