If we can guarantee that os.urandom() will never block or raise an exception when only poor entropy is available, then it may be indeed indistinguishably backward compatible for most if not all cases. Why can't we exclude cases when only poor entropy is available from "most if not all cases"?
Because if it blocks or raises a new exception on poor entropy it's an API break.
