The bulk update request #10973 is pending approval.
create implication mature_female (74082) -> middle-aged (0)
create implication mature_male (23142) -> middle-aged (0)
create implication mature_intersex (4005) -> middle-aged (0)
create implication mature_ambiguous (10) -> middle-aged (0)
Reason: The mature tag is invalid because it’s too ambiguous, but other age groups like child, young_adult, elderly, etc. have gender neutral parent tags, so I think it makes sense to have one for mature_* tags. The wiki defines mature as middle-aged, so that’s what I figured would work as a parent tag.
