Should tags like feral_to_anthro implicate feral and anthro and human_to_anthro implicate human and anthro? The wiki seems to support this.
In cases where they don't apply, shouldn't it be implied_transformation instead?

It sounds pretty logical to imply them, but are there any cases where it shouldn't be?

For example, could feral_to_anthro be tagged on a series of seperate images in a pool, where the first image may not yet depict a fully anthro character? Or would these images just not be tagged with feral_to_anthro at all to begin with?

That's precisely my question. Would they be better off not being tagged feral_to_anthro? Very few images aren't tagged with both. Imo if we're following twys, both would have to be present. Otherwise it's better tagged as implied_transformation or after_transformation.

If they're separate images, and the first one doesn't depict the transformation starting yet, it shouldn't be tagged with transformation. If there's enough to tell it's becoming anthro, then *_to_anthro and anthro would seem to be appropriate.

I'm generally for this idea, but I do sometimes find it difficult to tell when a post depicts to-feral vs to-anthro:
post #2552427 post #2555071 post #2498198

They're clearly in the middle of a transformation from human, but will they become feral, or end up more anthro? Difficult to tell by looking. Though I suppose that would more-so call into question the human_to_feral or human_to_anthro tag itself, rather than it implicating feral or anthro.

Something can depict ambiguous form transformation without necessarily being good for implied_transformation or after_transformation. Like Watsit pointed out, not all transformation is easy to tell if the end result is anthro or feral. Many pictures show enough for species_transformation and mid_transformation, but depending on the perspective and angling, or the specific way that artist drew that particular image, it could still be difficult to tell if it's anthro or feral.

I can agree though, that it seems logical to imply the base components to their respective *_to_* tags. Assuming there's no possible way for this to not be true, I'd support this.

On a related note, I'm surprised I've never seen a form_transformation tag. Species_transformation explicitly mentions it's not to be used for same-species transformation from/to feral, anthro, or taur. Unless I'm missing something, there doesn't seem to be a tag for that, though.

I have thought about this for a while. Sometimes, I will see the first image of a transformation pool get removed for not being relevant (the character being human) when the rest of the pool or series is the character turning into something. This is also a pain when someone only posted the first image of the series, so uploading the series results in it saying it is a duplicate of an existing deleted post.

perhaps imminent_transformation should be a widely used tag, but then it wouldn't always be tag-what-you-see. This is another one of my annoyances with e621. Something I would think could work is if pools acted more like posts. For example; a pool could take every tag from every post in it. Then, when searching, it would be turned off by default, but you could do type:pool or ispool:true and it will show pools rather than individual posts inside that pool.

But thats just asking too much…
