In the default setup, that last command will leave configuration files.
That's what resulted in the

rc linux-image-5.10.0-6-amd64 5.10.28-1 amd64 Linux 5.10 for 64-bit PCs (signed)

entries in the original post.

sudo apt purge --auto-remove

will get rid of the configuration files as well.

Indeed and tweaking a few configuration options goes a long way to
keeping your system lean and mean. Just in case anyone is interested,
here's what I have in my /etc/apt.conf

// Install packages based on their own merits, not because Debian
// or Devuan maintainers think you might want them.

APT::Install-Recommends "false";
APT::Install-Suggests "false";

// Remove installed packages as soon as they are no longer needed
// by other packages. This complements the above settings. Note
// that this only kicks in when installing or removing packages.
// It does *not* apply when just upgrading installed packages.

APT::AutoRemove::RecommendsImportant "false";
APT::AutoRemove::SuggestsImportant "false";

// Configuration files are tracked with `etckeeper` so there is a
// whole history of any such file in its repository. Whatever is
// *not* in the repository was either not worth tracking or a bit
// too sensitive (in which case some other backup mechanism would
// normally have been available or configured).

APT::Get::Purge "true";

Note, you'll need to install etckeeper to make that comment on purging
configuration true for your system. I do and tend to muck around with
the apt and network configurations quite a bit but for most part there
is a lot of configuration that I use as is.

Hope this helps,
