Timeshift mods to apt?

the file 80timeshift-snapshot that is added to /etc/apt/apt.conf.d is different from back in the day. I was checking one of my servers that was built with a very early butterbian-xfce and it had some script for purging old apt-scripted snapshots.

Is that not needed now? just curious because I manually purge any pre apt snapshots once I know my system is fine.
