The purpose of "Force JSON output to "{}" instead of "[]" if it contains either no properties or all properties are null"

What is the purpose of "Force JSON output to "{}" instead of "[]" if it contains either no properties or all properties are null." in \JMS\Serializer\JsonSerializationVisitor? I wanted to generate a plain array for my AngularJS service (it can expect either array or object) but it seems to be impossible to generate an array with JMS/Serializer. Therefore, I'm wondering, why is there such a hacky force from json array to object?

Currently, after serializing to json using JMS I then need to deserialize using json_decode($var, true) to obtain an array, and then do json_encode($var) to obtain normal array (not object). But this is a workaround, and not a proper solution.
