Deploying the same database to many different RDBMSs

With the idea of a generic Dacpac defined by international standard, comes the potential for a Visual Studio developer to use SSDT to create a generic database model to a SQL-92 compliant standard that can then be deployed to any one of the major RDBMSs.
