I don't think this is an advantage. Especially in the LOOP area, other
implementations are known to assign meanings to ambiguous forms. When a
user runs in clisp a program with was developed with another implementation,
it is better to give an error (or at least a warning) for ambiguous forms,
rather than returning a different result than the other implementation and
letting the user wonder why his program misbehaves.
