That is, people were often asking "defined @a" when they meant "is @a empty". The mistake was so common (you appear to have just made that mistake yourself) that "defined @a" was made to complain.

If the use of defined on aggregates doesn't match the common expectation; and the actual meaning is non-useful; doesn't it make sense to make it useful by making it match the common expectation?

That's the question. And I think you've supplied the answer, albeit unknowingly.
