Do you actually need this or you're just trying to address the TODO?

It's a 3rd if not 4th attempt from various "people" to address this TODO.
We should just remove this line instead.

I was one of the people that tried this. And also I have already sent
a patch to address the misleading comment to prevent future wasted 
effort. My patch is still on hold (LINK:
