"most software treats HTTP URIs as resource locators, not identifiers". And that is a general problem, not limited to namespaces. No non-digital resources - be they abstract objects like namespaces, or physical objects like ships - can be identified by a URI that is also a URL. By definition, the object identified is the object located. (And the resource located by HTTP is always a digital one.) Strictly speaking, namespaces are not really identified by a Universal Resource Identifier, they are identified by a namespace identifier that happens to have the same syntax as a HTTP-URL.
