What is the structure and meaning of 'having a just a few' in this paragraph?
The major shift here is that we treat both entities and users groups as very cheap resources. Instead of having a just a few and structuring around them, we define what we want and then structure the groups around them. The burden them moves from complex code to maintaining the structure. I find this a very reasonable tradeoff for a simple security model and the flexibility that it gives me.
