Indeed! I think it's already been decided that all non-mutating functions should be added to NodeLists and other list-like DOM objects. I believe Cameron is still working on the specifics of that.
Shortly before the LC#2 was published, I added an [ArrayClass] extended attribute that you can put on interfaces that are not defined to inherit from another. That causes that interface's [[Prototype]] to be Array.prototype instead of Object.prototype. It's then up to the designer of the interface to ensure that length and array index properties behave usefully (by defining a length IDL attribute and using indexed properties) so that the Array.prototype methods will do nice things.
The other construct that uses Array.prototype is platform array objects. They too have Array.prototype as their [[Prototype]]. Web IDL defines how array index properties and length are exposed on platform array objects so that they work with Array.prototype methods as best they can.
