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.
