The tag implication #63796 gibbous_moon -> moon has been approved.
Reason: Full moon, half moon, and crescent moon all exist and are implied to moon. Gibbous moon didn't exist until I created it just now, but it is the fourth main moon phase and should also be implied.
EDIT: The tag implication gibbous_moon -> moon (forum #407665) has been approved by @scaliespe.
