Personally I think that if it is shaped like a kilt, and swings like a kilt, it is a kilt, maybe just not a traditional one.

I see it kinda like chainmaille. Original chainmaille was rivited and was a higher aspect ratio than the more modern variation of tighter aspect ratio (inside ring diameter / wire diameter) and butted rings. Butted is easier and you can use materials other than mild steel, but it is not traditional and does not make suitable armor (I tend to make finger rings, and I am making a tie). But it is still maille by definition.
