What you are talking about is not uninstalling. It's disabling. Uninstalling should remove application.

What you are talking about doesn't really have a good definition. If a windows app consists of 10 files of which 9 are used by other apps too, does that mean removing the only unique file to the app? Should it remove any configuration related to the app etc

These are easy questions, and it's been a very common experience since forever:

Shared files stay until you uninstall all apps that use that

User config can be removed with an extra option
