Pros:

• Interface oblivious of implementation
• Allocators do not need manage area options with areas but only (more) areas.
• It becomes possible to duplicate layouts and their pointers without needing area options in function arguments.

Cons:

• Implies modifications to existing code and tests.
• Makes area interface closer to an allocator interface.

One big question for that is if we move these options to area creation, or multiply the number of area implementations.

It could be both in my opinion. It all depends whether it makes sense to factorize and/or optimize when we will have a real use case.
