Subclassing IMHO is preferrable because it is more general.

It encompasses instances throug singleton classes, when needed (for 
example in SPECIAL we are using this approach for dynamic consent).

Subclassing gives full flexibility and an amazing range of granularity 
choices, including co-existence of orthogonal formalizations.
