Push the rename warning down to the actual attributes, to avoid printing
it too early. Additionally, bind the warning to top-level static value,

The `import module args` pattern is useful for applying inputs from
outside of the module system, however it discards module location

`lib.modules.importApply` solves that problem by wrapping the applied
module using `lib.modules.setDefaultModuleLocation`.
This means documentation, warnings, and errors will show the correct
location.
