Never happened to me, maybe you uninstalled a metapackage?, not sure if packages installed by a metapackages are marked as automatically installed.

There is no package manager that uninstalls orphans unless you explicitly ask it to aside from nix and guix, also you can always just do "apt autoremove $pkgname" to do it in one step.
What's the alternative anyway?, Debian runs fine on my laptop but there's tons of bugs in my desktop (Gentoo doesn't count as an alternative to Debian).
