Self Reference Counter for circular Refference

That thing if you wanna iterate the same object on it self, wouldnt it be niche to have a object info node with a checkbox "circular refference" and set a default "count" value to 0. Then the Geomettry Nodes Tree should be automatically instanced if you set it >0.

Dont Know how efective and performant or possible it would be but it might be an alternative for an L-System especialy if there are mapping options. Maybe the input parameters of that instances can be edited with that kind of variable node too?
