I don't think that we need to propagate that revert for stable. I
reverted it in the devel tree because nobody wanted this upstream and I
couldn't test it. For that reason I didn't see the point for having it
in the RT tree.
However, if you want to revert it for stable, be my guest. It probably
will have no impact and if it will people might step forward and fix it
properly / upstream.
