Would that not be applicable for the recent thread about how to "reset" the
global object for re-use?

That's what i get for not reading ahead before asking questions :/. Undo
might not always be feasible because changes could have side-effects which
the global object does not directly see. For example:
var foo = {}; // in global scope. Global knows about foo, but...
// in client code:
foo.bar = ...;
the global observer probably could not catch that and therefore not
generically revert it.
