Actually the resource is not an echo system. 
The Instance lab, just provides a more comfortable way to duplicate objects and to tie them to another one in the group form. 
That new resource is far he/she gives to be an echo system in the true conception of the word. 
An echo system has several vegetation types, stones, trees, etc.... 
The only innovation, until the moment, is the instance lab, the rest it continues as before, besides with crash problems. 
As it is a version beta, we will await the definitive version and more innovations. 
In my opinion, only the instance lab non justice a new version, but a new release.
