I believe it's bad business to misrepresent an animal just because you believe it to be the same mutation. Compatible or not, different lineage and names should be maintained unless you are the originator of the project and choose to change the name.
I've seen advertisements of het candy being referred to as het toffees when they were in fact made with a candy. I just don't support misrepresentation, and the breeders who are doing it should know better.
