Still, no feedback on the effect that a truncate call is having on the DB and may be doing more than intended fairly easily. I am not in the hackers group so I couldn't say this feature would not be implemented. It just seems unlikely given the philosophies of that group.
I would not feel bad to have a more efficient option but possibly a more dangerous one. Projects/application could setup policies about what may be done in which way and what not.
