Thanks, much appreciated! You will be pleased to know that most of this is already possible but one has to build it. For example, anything builder related is same logic and hopefully you saw my road builder which is a simple example of building something with predefined blocks. If I recall @srek had some examples of parametric buildings.
Now, when you say controlled asset placement you are referring to distributing objects in numerous ways, right? There are many distributions in Neutron plus you can build any you imagine. Way more on your list that can be done already than not 🙂
For example, here is a log spiral distribution. Point is that, if it is based on any logic or math it can be built
