"Valid-Until:" was dropped from https://security.debian.org/debian-security/dists/bullseye-security/InRelease which fixes the 'apt update' warning.However it seems many files were immediately dropped from http://security.debian.org/debian-security/pool/updates/
I can't find the logic here, e.g.- http://security.debian.org/debian-security/pool/updates/main/f/firefox-esr/firefox-esr-l10n-fr_140.14.0esr-1%7edeb11u1_all.deb disappeared https://tracker.debian.org/news/1788460/accepted-firefox-esr-140140esr-1deb11u1-source-into-oldoldstable-security/ for the upload
- http://security.debian.org/debian-security/pool/updates/main/p/python3.9/ is 404 but http://security.debian.org/debian-security/pool/updates/main/p/python3.9/python3.9_3.9.2-1%2bdeb11u7_amd64.deb is still present https://tracker.debian.org/news/1752557/accepted-python39-392-1deb11u7-source-into-oldoldstable-security/ for the upload
