Birth Prototype is also marketed as a separate Rider, I don't know these could be possibly counted as simple form changes. You might as well say Faiz is a form for Kaixa.

Okay, I have no intention of separating the character page or anything, however Zangetsu Shin IS treated as a separate Rider in promotional materials (ala Black RX) and I think it should be separate just on the template here.
