While I agree that you loose control over certain details, we are overall quite happy using the frameworks.

The frameworks nowadays provide the ability to call procedures if required - but using the objects directly is more
convenientfor the developers. SQL procedures add (just like a CTE) an additional layer to the application design which
needsmaintenance. That's fine if it really helps overall but we try to avoid it if it isn't needed.
