It needs a namespace, but it does not need a globally shared namespace.
Indeed, the man program should not have mutate access to the standard manual
page space.

The fundamental objection is not to namespaces, but to global namespaces
(because these are prone to misuse by well-intentioned humans) and in
particular to globally shared non-constant namespaces. A namespace that is
pure constant (i.e. in both names and content) is not a communication
channel.
