As a question, if the node lists were implemented as catchalls, how would the behaviour differ from current NodeLists?  The only change I can see would be the loss of the host object exceptions in the ES spec, but that just puts you in the position of having semantics that match the current host object behavior in those implementations that already allow array functions to operate on host objects.
