The tag implication #40236 popped_navel -> navel has been rejected.

Reason: A popped navel implies the existence of a navel, therefore there ought to be a tag implication from one to the other.

EDIT: The tag implication popped_navel -> navel (forum #312339) has been rejected by @bitWolfy.

If popped_navel is the same as an outie_navel, it would probably be better to alias popped_navel -> outie_navel (or alias outie_navel -> popped_navel if folks prefer that alias).
