Module addReads is important when generating bytecode in your own module 
with references to classes in modules that you don't read. Another 
example  is where you create method handles for a method in a class that 
is a member of a module that you don't read.

The equivalent ModuleLayer.Controller addReads is the container case. 
There was a recent thread here with Alex Svirivov where he's prototyping 
creating a container creating a module layer for a web application. The 
container may need to use addExports to export the web application entry 
point to the container and (depending on how the container invokes the 
web application entry point) it may need to read the module in the child 
layer too.
