I think the solution suggested by drawks seems clearly the correct choice:
> I think the proper solution would probably be to package both a "-full" and "-minimal" version of the software and utilize Debian package meta-data fields to define a Conflicts relationship between the packages and tag them also both with a Provides for keepassxc and also add a tag Replaces: keepassxc to the -full build so that during a package upgrade an existing user would be provided the version that continues to provide the features of the package which is being upgraded/replaced while new users can choose for themselves which of the versions they'd like to install

Why would this _not_ be the obvious choice?
