I wouldn't say the taur content is slim by any means, there are 12 npcs in Trials alone that fit the quadruped body type typical of a tauric nature not to mention the plethora of scenes that require Steele to have a tauric/naga body outside of those 12. You can even bed a gosh dang caterpillar (Xanthe is criminally underrated btw). That's a shame though, as I quite enjoy the plethora of taur stuff already in CoC2. I know this is a big ask, but if someone were to build taur TF support for the game - handle scenario writing, coming up with the necessary flag/tags checks, descriptions for the champion, etc - would it then be possible to add it in?? It just sounds like the decision not to have it was simply because there was no one to write it up, but if one were to do so then...?
When they say it was not really supported, they are referring to the vast majority of scenes in TITS not even having variations for non-bipeds, despite those body types being available for most of the game's lifetime.
That kind of support disparity is what COC2 chose to get away from. Force all writers to double/triple/quadruple their workload by writing non-biped variations of every single scene, hire people specifically to write the massive amount of variations (and hope they can keep up with the workload consistently) and get primary writers to review and accept every single one, or decide to not provide those body types in the first place.
