You're welcome.

AFAIK, "apt-config dump" is meant to be for apt-get - at least historically.

After I sent my previous email, I thought that it must mean that deb
files of packages installed with apt-get would also not be saved. I
now have some upgradable packages again so:

# apt-get clean

# apt-get dist-upgrade
...
3 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
...

# ls /var/cache/apt/archives/
dnsmasq_2.76-4_all.deb dnsmasq-base_2.76-4_amd64.deb  lock  partial/
ubuntu-keyring_2016.09.01_all.deb

# apt-config dump | grep Keep-Down
Binary::apt::APT::Keep-Downloaded-Packages "0";
#

So there's now a disconnect between apt-get and apt-config :(

Thanks. Force of habit...

Good test. Thanks.
