Oh no.
If you update or download with apt or dselect, then apt or dselect get
Packages_du.gz befor it download the .deb files. So it can check the space on
the disk and make warnings. 
(dinstall make the Packages_du.gz (like Packages.gz) from the .deb files.
dinstall get size.gz from the 'news' .deb files or make a size.gz from the 'old'
deb files)
But if you download from the ftp-server by yourself and install the dep file
with dpkg, then you haven't a disk check. Only if the du information is in the
deb file, dpkg can make a check.

I say: Put the du information in the .deb files and make (on master) from this
the packages_du.gz file. In this case all installer (like apt and dselect) can
download packages_du.gz and make a check befor it download all .deb files. But
also dpkg can check the disk space (with the information in the .deb file)

If we have du information only on a seperate file, only dselect and apt can 
make a check :-(
