Thanks, David. I suppose I could have looked harder. That's really great too. I think/hope this all just means they plan to keep the Platypus in the lineup for a while. Going to the trouble of making the lugs, that is. (Unless this is just a carryover from previous mixte models, as someone suggested.
As to the too- utilitarian look, maybe the sockets could resemble the OG Clem (abandoned big bike lugs, I believe), with a scallop and cutout. (See pic.) But then, we'd want the top of the seat stays to look the same. Kind of a can of worms, I suspect, that could easily start to get too "fancy," and drive up costs.
