Actually, I was wondering the same thing, maybe for a different reason.
Exposing the backend internals could have security implications (though
don't make me concoct a scenario to prove it ;)

Although it might have some usefulness for debugging, I think it should
not be an "installed by default" feature, so istm would be a great
candidate for a contrib/ function or library. If someone needs it, it is
almost immediately available.
