My proposal for solving these problems would be to explicitly

This would allow to design applications that can fail

a programmer error.
What do you think? Does the idea have merit? Should I make it
into a DIP?
Pragmatic question: How much work do you think this will require?
Because writing a generic wrapper that you can customize the
fault behaviour for using DbI requires very little[1].
