To be fair, it's not like if you were a fully anthro rabbit would matter since they could write any and all scenes in a way that completely ignores any and all bodily features. Not only that, maybe there wasn't enough people who wanted to be full-on rabbit people for them to do it. It's like the time Fen asked if people wanted an elephant TF in TiTS, knowing they weren't going to have any content that acknowledges the TF in the first place. Most people didn't really care, and you have to think about the writing process behind all of that. When you're writing any of these scenes, whether they be codex entries, sex scenes, interactions, you're gonna have to write them all in a way that would easier plug-and-chug different adjectives for all of the possible TFs currently in the game. When you have to do that, scenes get more generic because they have to work with all TFs without breaking, or you end up writing special scenes for TFs.
