It should be a separate command, I think.

I need to clarify if your disclaimer (for changes to Emacs) is
sufficient to install these changes.

I don't think it's useful to duplicate `gnus-group-list-groups' here.

I'd simply use `(1+ maxlevel)' unless maxlevel is >= `gnus-level-killed'.

Instead, the prefix arg could be `activate', i.e. only call
