I think it's misleading to think about switching databases on an ongoing application as the use case for database independence. More important use cases: 1. Using SQLite for unit testing and a real RDBMS for integration testing, acceptance testing, and production. 2. When you are writing a library that will be used by different projects, not all within a single organization (e.g., a Free Software project). 3. When you are providing a product that the end-user may want to use with different choices of database (e.g. forum software, Nextcloud, etc.)
