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

*. Should I use exception for error handling?

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...
