A good API could change the implementation without changing the signatures,
they not are strictly related, it's not the only practices to do the things.
How is related from the data storage and API ? At API level, we don't do any
assumption on how data is stored or how is the internal implementation,
these are things to a lower (not API) level.
I think could be possible to write a sort of more abstract general API on
top of existent for expose a bunch of general "services" with Drupal
versions compatilibity in mind. Could be a plugin.
