Yes. The issue is the time required to gather that
information. For larger packages like xbooks, that may well take over
a minute on slow machines, which is unacceptable if a large number of
packages are to be ugdated.

If packages were to include a du -S output (unlike the du -s
output included by some helper packages before), this script, a
modification of Kai' script, could be used to gather the data. This
has yet to be discussed and passed into policy.
