It's useful to know *why*.
The less the importer knows about the details of the imported
module, the less your mental-load and scope for mistakes.
In the example: Module: ConfigInput
was designed so that no importer can look inside the exported:Frame.
Then there's the compromise possibility of some systems:
you can look inside but you can't touch it. I.e. read-only.
