It means that the namespace itself has subscriptions=no, and there are
no "parent namespaces" with subscriptions=yes.

I guess you'd want INBOX. namespace to handle the subscriptions here,
but it doesn't work like that because in some configuration it could be
ambiguous which namespace to use.. You'll need to create a prefix=""
namespace to handle the subscriptions. For example:

namespace {
  prefix =
  list = no
  hidden = yes
}
