We (especially Timm) thought about something similar for the dec3d group: http://www.w3.org/community/declarative3d/wiki/Base_Types

Adding interfaces to the DOM when they are clearly related to the Web and Web documents is ok, but I think we need to show caution adding 6 interfaces that have broader use. I believe this is why the WebGL group discussed the *Array classes with ECMA.

I'd suggest a good first step would be to ask about this on es-discuss.
