The line is blurry in this regard but I've always felts they were subfiles. The decision to go primitive was made before my tenure as Admin so I went with it. As things have gotten more and more complex in the logo space I'm starting to feel that they are less in line with the primitive ecosystem. I also find the concept of primitives as templates distasteful (although I can't really articulate why).
Example: I have a list of 30+ files from one author that are logos or pieces of logos. Many of these logo pieces are used once. This is not the reusability standard I would expect in a primitive. And before someone complains about many different subfiles for the same logo, this is one of the things the part review process is supposed to catch.
