I agree with Bret in that it's not harmful (if anything, maybe slows things down a tiny bit). I'd consider removing it and if you happen to see the same problem again, please report it (regression!) and the workaround can be re-enabled, which would be a quick action on your side.
My rationale is so cruft is not accumulated; particularly since at this point it'll be like "what does this do?" "oh, doesn't do anything anymore but it's always been there".
Git will take care of keeping the history for us
