Most, but not all, are in /usr/share/doc/apt/examples/configure-index.
Those ANSI colours haven't yet made it in, for example.

AIUI you're expected to add a file, say, 90-my-opts into apt.conf.d/
with Upgrade-Allow-New "true"; in it.

The downside is the more high-level packages you have installed,
the more dependencies, and a more difficult path to resolution.

On my system, w3m is only Recommended for installation, so it's
effectively top-level. It has few dependencies, and those it has
are the sort used by many packages. So removing w3m has liitle
effect on the rest of the system:
$ apt-get -s purge w3m
[ … ]
The following packages will be REMOVED:
w3m*
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
Purg w3m [0.5.3+git20210102-6]
$
OTOH, if you remove guile-2.2-libs, you must also lose mailutils and
libmailutils7, which depend on it. Having removed them, apt finds
that there were other packages only installed to satisfy mailutils,
so these are no longer necessary either:
$ aptitude why gsasl-common
i emacs-gtk Depends emacs-bin-common (= 1:27.1+1-3.1+deb11u2)
i A emacs-bin-common Recommends mailutils
i A mailutils Depends libgsasl7 (>= 1.1)
i A libgsasl7 Depends gsasl-common (= 1.10.0-4+deb11u1)
$ aptitude why libntlm0
i emacs-gtk Depends emacs-bin-common (= 1:27.1+1-3.1+deb11u2)
i A emacs-bin-common Recommends mailutils
i A mailutils Depends libgsasl7 (>= 1.1)
i A libgsasl7 Depends libntlm0 (>= 1.2)
$
So it can get rid of the lot:
$ apt-get -s purge guile-2.2-libs
[ … ]
The following packages were automatically installed and are no longer
required:
gsasl-common libgsasl7 libntlm0 mailutils-common
Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
guile-2.2-libs* libmailutils7* mailutils*
0 upgraded, 0 newly installed, 3 to remove and 0 not upgraded.
Purg mailutils [1:3.10-3+b1]
Purg libmailutils7 [1:3.10-3+b1]
Purg guile-2.2-libs [2.2.7+1-6]
$ apt-get --purge autoremove
[ … check the list carefully … ]
Cheers,
David.
