Urist is a random name the game can assign to npcs. There are many other ‘weird’ or noticeable names out there, if you just look hard enough.
Otherwise, i don’t think there are any other boons you get from being a deputy. As you said earlier, Bots will recognize you and leave you alone, even if you’re the one breaking the law, but there aren’t any new missions or so from what I know.
Also, technically you can already conscript other npcs by speaking with them, you know that, yes?
