The problem seems to be that action "org.debian.apt.update-cache", contained in file /usr/share/polkit-1/actions/org.debian.apt.policy, now has all the "allow"s set to "auth_admin[_keep]" instead of "yes". Changing these by hand brings back passwordless checking of repositories. This .policy file is provided by package aptdaemon.
I'm still wondering, though -- shouldn't polkit-gnome-authorization display all the entries in /usr/share/polkit-1/actions in addition to the ones in /usr/share/PolicyKit/policy?
