How would that interact with architecture-based constraints (e.g. 
issues porting libraries in their entirety because of 
architecture-specific limitations, missing assembly 
implementations, etc.)?

Is it possible to ensure there is a well-defined "pay for what 
you can" separation of concerns, as well as "pay-as-you-go"?

P.S. I think you should call the library Asaph, it's more 
distinctive ;-)
