Suppressing warnings against a namespace does not suppress warnings against inner namespaces, i.e. namespaces that share all namespace segments with suppressed namespace.

Summary
Suppressing warnings against a namespace does not suppress warnings against inner namespaces, i.e. namespaces that share all namespace segments with suppressed namespace. I found this behavior to be unintuitive and wanted to update the documentation to help other people with the same confusion.
I spent a bit of time reading over the C# language specification trying to find the best term to describe namespaces that are part of another namespace. Let me know if there are any preferred terms for them.
