That's pretty much why I used dselect all the time.
These days I maintain a set of personal meta-packages that lists all
the software I know I want installed and about once a quarter I do
something like "apt-mark showmanual | grep -v mrc-$(hostname) | xargs
apt-mark auto" followed by "apt autopurge". (A few more steps in
there like checking for transitional packages I can now remove and see
if I am going to remove any packages I installed adhoc and decide I
now want to keep.)
