Why are they all just "illegal protogen" what does that even mean [crying emoji]

I don't like using that term, but I do know what it means. It's when a protogen's design goes against the official guidelines for the species (there's a summary on the wiki ).
Well there are three ways to go against the guidelines, if the design has a trait that is forbidden or restricted, then it is illegal; if it has a trait that is not on the list, it's unofficial; if it lacks a trait that is required, it's not a protogen but something protogen-like, if you call that a protogen, it's illegeal*
*.-the last paragraph is not as fact based as the first and is just My understanding of things
