I'm not exactly following how partial interfaces are problematic here.
Once you gather them all you have a complete picture of the object,

If this is about internal slots, I would be interested in exposing those in IDL.

  class Event {
    String [[type]];
    get type()
    set type()

Combined with convenience syntax that could make the full structure of
a class much more clear.
