Fairly agnostic about this, given that you can express most combinations within
the { ... } form. But I'll think about it.

Well, the thing is it isn't consistent with the destructuring meaning: dropping
the curlies here means extracting a single export (aka property), which is not
what it means in destructuring assignment/binding anywhere else.
But that said, the convenience may well still trump the inconsistency.
