Are provisioners really "a last resort"?

I was looking at the getting started guide here: https://learn.hashicorp.com/terraform/getting-started/provision

which links to this page on provisioners: https://www.terraform.io/docs/provisioners/index.html

which indicates that provisioners are a “last resort” which suggests to me that provisioners should be a special case thing for most users, but putting them in the getting started guide suggests they’re one of the first things you reach for – is there some cognitive dissonance among the documentation writers?
