I believe this is the wrong direction, even if we rewrite the module
in the revised datastores document and split it into multiple modules.
A simple list of implemented datastores is cheap. It is flexible. It
does not require explanations and rules how definitions must be split
into modules that finally must be remembered and checked still in 5-10
years from now. I firmly believe that these types of 'optimizations'
lead to creeping complexity down the road. Lets not create CLRs how
modules must be structued, named, etc.
