If I understand namespaces correctly, they are only a way to provide 
unique names. If so, a particular namespace is not a "coherent" set of 
classes and properties. (Although this usually is the case, a namespace 
does not imply this.) The SKOS "concept scheme/space" does have this 
stronger meaning (if I interpret the spec correctly).

Probably it is a good practice, but if the above argument holds, the 
concept scheme and inScheme property are still needed to provide the 
stronger meaning of a coherent set.
