So why would someone try to represent a hash with an array of two element hashes each with the keys "key" and "value"?

"Represent a hash" makes no sense. I presume you mean "implement an associative array".

Someone would do that if they wanted to preserve the order of the tuples. We've covered this multiple times already.
