Obviously. And yours seems to be good experiences with good
implementations. What does that show us? Apart from that both good
and bad examples exist?

Precisely. If the problem domain is a good fit for the RDBMS/DSL,
data that naturally wants to be in 'tables', then it *may* be a win,
even after factoring in the inevitable overhead of overcoming
packaging mismatch. If the original problem is not naturally "table-
oriented", and many are not, then it's just not going to be a win.
