Uncompressed Bytes metrics

Is there a way to get the uncompressed sizes (HTML,JS,CSS) for the resources from the agents ?

There seem to be some references to $request[‘objectSizeUncompressed’] in breakdown.inc file but seems that may only be set for non gzipped resources.

If this is accessible to the agent (especially when save response bodies is true), I can try putting a code review if someone can point me what sections of code I should look at - We wanted to enable this on our private instance.
