Neither maintainer scripts of linux nor grub2 contain code that could
remove just /etc/kernel/post{inst,rm}.d/zz-upgrade-grub, which is what
you claim you see.  Please provide evidence instead of paraphrasing.

Aka:
- dpkg -s grub2-common
- ls -alR /etc
- grep -r /etc/kernel /var/lib/dpkg/info
- zgrep /etc/kernel /var/log/apt/*

Also code search does not find anything else targeting the
zz-upgrade-grub files specifically.
