How do I completely reset the system configuration of a single package (gdm3)?

I'd like to completely reset the system configuration of the gdm3 package. I mean all the files under /etc/gdm3/, /var/lib/gdm3 and anywhere else it has installed files. Changes files should be reset to their original state, deleted files restored, and added files not from the original package removed.
Neither dpkg-reconfigure gdm3 nor apt install --reinstall do this. I don't want to purge and reinstall the package, because of all the dependencies that will remove. I only want to wipe the slate clean for one particular package.
In this case the package is gdm3, but I think there might be a generic way to do this for any package. I realise that configuration that's coupled to other packages (eg. Systemd service status) and user configuration under /home won't be handled.

The following command will ask to replace chanced configuration files with defaults:
sudo aptitude -o DPkg::options::=--force-confask reinstall gdm3
However, as far as I can tell, it will not delete extra configuration files. If you know where the configuation files are, you can just delete them yourself before running:
sudo aptitude -o DPkg::options::=--force-confmiss reinstall gdm3
To see the available --force- options, use:
dpkg --force-help

This doesn't revert eg./etc/gdm3/custom.conf, which is definitely part of the original installation and not added by me.

(I am starting to wonder if I have picked a particularly bad package for this question, because maybe a lot ofgdm3config is done by post-install scripts which might do their own checking to avoid clobbering...?)

Apparently the--force-confdefdoesn't act the way the description sounds like it should... change to--force-confask. Or delete all config files and try--force-confmiss.
