Feature or enhancement

SimpleNamespace is used as a simple data record type, a simpler alternative to named tuples and dataclasses. Although it is easy to create a copy of a SimpleNamespace instance with modified attributes (SimpleNamespace(**vars(ns), attr=newvalue)), it would be convenient if SimpleNamespace be supported in copy.replace() which already supports named tuples and dataclasses.
