Really? I don’t know. I liked being introduced to it and it seems unlikely someone would realize that there was a new thing that they could do unless Discobot pings them to say:
Hey, there’s a new training module you can do now about polls, if you’re interested [do this]!
Yeah, realistically, very few people take the advanced tutorial - I was 165th to get the badge when I completed it yesterday vs 900th for the basic one - and many people may already be TL 1 by the time they take it, so that leaves a tiny subset who fall into my category.
I’m also not sure if Discobot is used widely on other Discourse sites. Maybe some sites encourage new users to take both tutorials so they have a higher incidence of getting stuck…
But this ties into feature support. Do you want users to know about the feature? I assume so, since you include it in the tutorial while the date/time tool and the blurred spoiler tool and the code markup tool aren’t included.
So, if you want people to use it and know about it, particularly when it’s hidden two clicks deep in the cog menu, don’t exclude them because they’re TL0. 
They won’t be for long if they’re that interested in learning about the platform that they found the advanced tutorial so early.
