I don’t know of a specific reason why we don’t use <position> on perspective-origin.

It looks like Gecko parses it the same way as transform-origin but without the z coordinate.
WebKit and Blink use a special function just for perspective-origin. Both can probably use <position>.

Would implementations be willing to change?
