Comment 1 for bug 1737013

Both make sense. There was also the idea of wiring with group vars, but if it's possible to avoid a group var for that, that's even better.

I'd be enclined to do a cleanup of the vars later, right now I'd say it would make sense to pass all the required variables to the include_role when we do it, because it's an approach we have taken in the past already:

This sounds a serious problem though, and I am surprised no-one got the issue before that.
