It's really, really not. Every single method of avoiding comma-based ambiguity is dependent on a consistent system being employed throughout the work. If I write "his parents, Mike and Elaine", it's only clear that these are two people if the serial comma appears everywhere else. Otherwise it could just be four people and a lack of a comma. Clarity is defined by consistency.
