Have not found anything related here Would appreciate if somebody can explain why this happened: wondering if this is expected and should be documented.

Test script:

$array = [
    ['ids' => [1,2,3,4]],
    ['key' => 1]

var_dump(http_build_query(new ArrayIterator($array)));

Expected result:
string(92) "0%5Bids%5D%5B0%5D=1&0%5Bids%5D%5B1%5D=2&0%5Bids%5D%5B2%5D=3&0%5Bids%5D%5B3%5D=4&1%5Bkey%5D=1"

Actual result:
string(0) ""

The third bullet point is the one that affects http_build_query().

The quoted section from the migration guide references ArrayObject, but makes no mention that the change also applies to ArrayIterator.

Ah, yup, that is exactly what it says. My brain likes to bundle them together.

Presumably it's the same underlying change affecting both.
