Each call to fully_expand_fragment is something unique, interesting, and requiring attention.
It represents a "root" of expansion and its use means that something unusual is happening, like eager expansion or expansion performed outside of the primary expansion pass.
So, it shouldn't hide under a generic visitor call.

Also, from all the implemented visitor methods only two were actually used.
