These are some future ideas about the next iteraction of modules, have a modules section that can control how modules are loaded, used, etc.

modules = {
// Reload the modules in each request, great for development
autoReload = boolean,
// exclude, an array of module names to exclude from the loading procedures
exclude = [
],
// An array of module names to load, by default, the module service loads ALL located modules.
include = [
]
}

Same translates to XML

<Modules>
  <AutoReload>true</AutoReload>
  <Include></Include>
   <Exclude></Exclude>
</Modules>
