Yeah, it is better to revert it as ideally that is not required after
this patch and that is what I have tried to convey above ("Ideally, it
would have obviated the need for my previous patch which
got committed as 778e78ae." (The commit id is for branch 10,
otherwise, it is same as what you mention.)).  I have locally reverted
that patch and then rebased it on top of that.
