The term "pointy_ears" in itself is body-type neutral. It could refer to anthros, ferals, humanoids, taurs, or any other body type.
But "pointy_ears" is currently aliased to "humanoid_pointy_ears".
Which means whenever someone tags "pointy_ears" on an anthro/feral character, it gets replaced with "humanoid_pointy_ears".
This tagging mistake is currently present on at least 1200 images, evidenced via the search: humanoid_pointy_ears -humanoid -human solo ~feral ~anthro

Users are supposed to use "prick_ears" for non-humanoids, but it seems many users are unaware of it and don't expect their "pointy_ears" tag to turn into "humanoid_pointy_ears".

These 1200+ mistagged ears could be fixed via a tagging project, and if a de-alias/implication were implemented could both prevent the mistake from being made by users in the future, and make ear tagging more intuitive to users who aren't aware of the "prick_ears"/"humanoid_pointy_ears" tags. Here's 2 possible ways it could be done:

Conservative suggestion:
Dealias "pointy_ears" from "humanoid_pointy_ears"
Implicate "pointy_ears" to both "humanoid_pointy_ears" and "prick_ears"

Bold Suggestion:
Dealias "pointy_ears" from "humanoid_pointy_ears"
Alias both "humanoid_pointy_ears" and "prick_ears" to "pointy_ears". This reduces 2 tags, merging them into the more intuitive "pointy_ears"
Users who are searching e621 can then use a 2-tag combination such as "pointy_ears humanoid" or "pointy_ears anthro" or "ponty_ears humanoid anthro" instead of needing to know what the different body types' ears are called.

Other suggestions, comments, or arguments for or against are being requested.

I don't see the problem.
Plenty of creatures have a humanoid_penis, despite not being humanoid.

prick_ears aren't just "pointy ears on non-humanoids".

As the name(s) implies, the ear is "pricked" or "erect", tapering at a pointed end. They are always upwards pointing and upright.

These would be pointy ears on a non-humanoid, but not prick_ears:

I guess it's because the tag's description says "use this tag only on humanoid, elf, demon, vulcan and similar creatures with pointy ears"

But as Caroway's search showed, the tag is being used frequently for characters without humanoid ears, people just use it for any ears that are pointy without knowing about the alias. If a tag has been misused a dozen or so times, then that's just a few posts that need fixing, but if it's been misused over a thousand times, then the tag needs fixing.

Unaliasing and having humanoid_pointy_ears and prick_ears both implicate pointy_ears is a good solution.

Okay, now that you mention it, that description seems oddly restrictive. I don't see why it couldn't be used for taurs who have elf ears, for instance.
