I agree that it could be a nice feature. But it reminds me a quote from a C++
FAQ I read once.

Ans. The real question is can I afford stack unwinding here...

The situation is similar here. When you want something in database, one
question is to ask is do I need MVCC here?
Of course depending upon the application context the answer well could be yes.
But at a lot of places, this could be easily be managed in application and
probably better be done so.
Personally I do not think managing such information in application is an
hack.
Just a thought...
