Not a problem, but this would improve maintainability for a moderate to large project composed from multiple libraries (both regular C# netstandard and razor libraries).

Describe the solution you'd like

Blazor's Razor markup doesn't support partial namespaces. I am building a suite of libraries and would like all of them to share a single top level namespace, say foo. The libraries would then apply namespaces:

• Library 1: namespace foo.bar1 with components Bish.razor, Bash.razor and Bosh.razor.
• Library 2: namespace foo.bar2
• Library 3: namespace foo.bar3

The app consuming the libraries would then place @using foo and use the remainder of the namespace in a component tag. So for instance using the component Bish from library 1, the markup would be <bar1.Bish ... />.

This is geared towards maintainability and clarity of usage.
