The UNH tests do get things wrong on occasion, but the 1.4c specification in section 5.15.2.1 states:

5.15.2.1 Identify Namespace data structure (CNS 00h)
...
capabilities that are common across namespaces for the controller. If the controller does not support the
Namespace Management capability and the NSID field is set to FFFFFFFFh, then the controller shall abort
the command with a status code of Invalid Namespace or Format.

So I think the test is correct here.
