Because every single database vendor will try to lock down their users to their DBMS.

Oracle is a prime example of this. Stored procedures are the place to put all business logic according to Oracle documentation.

This caused backslash from escaping developers who then declared business logic should never be inside the database. To avoid vendor lock-in.

There's no ideal solution, just tradeoffs.

I mean, that already happens. It's quite rare to see someone migrate from one database to another. Even if they stuck to pure SQL for everything, it's still a pretty daunting process as Postgres SQL and MSSQL won't be the same thing.

I'm not discounting the level of effort involved, but I think the reason you don't see this often is because it is rare that simply changing DBMS systems is beneficial in and of itself. And even if it was frictionless (ie: if we had discovered ORM Samarkanda), the real choices are so limited that even if you did it regularly, you would soon run out of DBMSs to try.
