The main reason that was not done so far is that you can be root
without using sudo, and this option wasn't default so this part was
overseen.

That's another heuristics that I could add to default pbuilder 
which might or might not satisfy everyone's needs.

The most reasonable default value would probably be 

export BUILDRESULTUID=${SUDO_UID:-0}
export BUILDRESULTGID=${SUDO_GID:-0}
