This has been known for at least a decade now, and no changes have been made. I've even seen estimates on how little it would cost to modify the feed, and it's negligible, but any extra cost is too much cost I suppose.

That's why carbon pricing is such an interesting tool. Make the desired option the cheaper option and it will be adopted.
