If that's the general consensus of the community, perhaps we should rebrand the morph as a single thing, like with pastels, then have separate lines to offer a distinction between them for those who have been maintaining a "pure" line.
As an example, we rebrand them Plattys, so one can have a Butter line Platty, or a Lesser line Platty. Personally I like this name because it works well with Ralph's original Platinum (Platty Daddy), and the het daddy gene.
Then you end up with 3 options, Plattys, Butter Plattys, and Lesser Plattys. Which leads to a group for undetermined snake lines, but maintains the line distinction, as with Pastels.
