You are missing the point, I think: this variable's name is known widely enough to make it a de-facto public interface. Changing its name without an alias will cause breakage to many people's configurations. However I dislike use of this variable in people's configurations, I cannot break them all just because I dislike that. IOW, it's a question of being fair to our users, even if they do something we don't endorse.
