There's one remaining zone which has the problem, namely Asia/Tehran, but I don't think your 400-year change fixes it.
Yeah, that zone doesn't work to a Gregorian-based rule.
So, I'm hoping that your fix is no longer needed, in that the other two patches have fixed things in a different way.
I don't think that follows. Even if the 400 year hack is no longer used for any current zone, that doesn't mean it'll never be applicable in the future. If zic is to retain the logic for the 400 year hack, it ought to be the robustified form of the hack. -zefram
