The bulk update request #9314 is pending approval.
remove alias aeromorph (0) -> living_aircraft (3435)
Reason: I'm not sure why dire_aircraft have their own separate tag identifying them, but both anthro_plane & Aeromorph have to alias into Living_aircraft. It seems like Aeromorph was originally aliased into Living_Aircraft around 9 years ago (topic #12353), when according to the users in the thread, "anthro_plane" existed as its own tag (while dire_aircraft did not), and both anthro and dire aircraft had a noticeably smaller tag count. At some point after, anthro_plane was also aliased into living_aircraft, and currently over 6 of the 44 pages in aeromorph are tagged with dire_aircraft. As well as such, the other tags created from this thread "terramorph" (which was only just removed today, after being used on a single image) and "hydromorph" (which to the best of my knowledge was never used), left no impact, so it doesn't seem reasonable to continue to lump in both humanoid aircraft (which *also* exists as a tag, and seems to rarely be used) with dire_aircraft, seemingly solely as a result of how rare the distinction seemed to matter in the past.
At the very least, the tags for everything involving living_aircraft could greatly benefit from being cleaned up. Like the tag "Living_airplane" *also* existing, despite offering seemingly no further distinction than "no anthro helicopters," and itself being rarely used.
TLDR: Aeromorph should exist as a tag referring solely to anthro aircraft, as dire_aircraft exists solely for feral aircraft, with both implying living_aircraft.
