anatomy_mistake is currently used to identify avoidable/unintentiontal anatomy drawing mistakes, but I see there's an alias suggestion for it to questionable_anatomy, which is a different set: questionable anatomy can apply to many more things, often intentional and not mistaken. (An example of questionable but intentional anatomy not covered by anatomy_mistake is post #14264.)

Can this alias be removed, or changed to an implication?

Alternatively, I temporarily tagged the current anatomy_mistake set with avoidable_anatomy_mistake, to preserve the set and replace the former tag if the alias is accepted.
