I am currently an admin, CheckUser and 'crat here, as well as other roles on Meta (and a few other wikis). Most recently, I was elected as a steward. Since this is one of my home wikis, I am not permitted to take action here as a steward.
My main tasks are currently keeping the cleanup backlogs just this side of the apocalypse. {{Backlog}} shows the tasks where non-admins can help with these backlogs.
My main challenges are vandalism (mostly bad page creation); keeping up with new page patrol and verifying media uploads; and copyvios (especially in the cookbook).
If you are a vandal, you'll get one warning. If you're particularly vulgar, you won't even get that.
I have rather strong views on rights. If you need them, are trusted, and active, you should have them. You only need the tools while you meet those requirements - if you're no longer trusted, active, or don't need them you shouldn't have them.
This is the correct reaction to removal of admin tools for inactivity.
