I agree with the principle of not tying the API to a specific library.  
To the extent that this WG provides feedback, I would be inclined to  
keep the API independent of Berkeley DB. That said, there is inherent  
benefit to starting with an API which could be easily implemented and  
be mature enough from the beginning.

Therefore, my approach would be to use a subset of Berkeley DB's API  
that is justified based on the requirements considered appropriate by  
this WG.

You got it right.

To be precise, MySQL has deprecated support for BDB as a storage  
engine starting with v5.1.12. Who know what will happen in the future  
though?
