Package: adduser Version: 3.121 Severity: important add_extra_groups is the only multi-word command line option that uses underscores instead of hyphens to separate the words. We should rectify this asap.
According to codesearch.debian.net only the fish package contains the literal add_extra_groups, so we can quickly deprecate the old form after changing to the new form. I think we can immediately throw a warning if the old form is used, and them remove the old form in bookworm+1.
