Yes, I looked a couple of months ago in the patch comment #3, and it didn't work, figuring out why this didn't work lead to the patches on errno etc. Something in the option mechanism was causing this to be overwritten, I didn't figure out how to fix this cleanly. I would guess that, maybe, the new option handling mechanism makes this easier.
