domain scoped is a bit of a hidden header scoped feature, where header name == Host. (that may be a tomcat specific thing, but seems to be pretty consistent in the servlet spec for the implementation of getServerName).
The one big usecase I see with domain scoped is being able to scope beans based on tenants in the system. Suppose you had URLs like tenant1.mysaasapp.com tenant2.mysaasapp.com Based on the incoming URL, I can scope objects to the actual tenant domain within my SaaS application. Pretty neat idea. As far as header goes, I can think of use cases within feature toggles, and impersonation support that may be useful. Even localization support being to drive i18n configuration on the backend based on the Accept-Language header.
