I don't know... the places I've worked where there was that much of the application shifted into the database layer, there would be no Flyway. You'd be happy to get write permissions, let alone permissions to update the structure. Perhaps correlated, those organizations managed the versioning part through a heavy-handed change management process, ie. humans. Perhaps in some places it's cool now to do this, but for me having the entire application logic modeled in the database will always be associated with painful enterprise culture.
