In one of my old inherited servers, I execute
apt-mark showmanual
And I get a list of near 100 entries.

Are there any potential issues in the future if I have one package (or a large number of packages in my case) marked as manually installed?
Should I mark them as automatically installed (and attempt to remove them later using autoremove)?
Actually it's a Debian 12 Bookworm
