Portability across RDBMS-es is far more often planned for upfront than
it is actually used. But if it is really desired it can easily be
achieved in the data access layers. Not exactly rocket science, I have
done it in many systems.

Treating the data store as a separate deliverable gives a much more
important type of flexibility: being able too swap out (parts of)
applications that access the data since their interaction with that data
is well defined instead of an implicit artifact of the applications
themselves.
