Maybe it'd be a good idea to do that anyway. Wholesale or retail, finding such names and knowing it's from a NP member indicates that the owner is open to any possible business proposition.
In many cases, there may be many domains that are parked or sold that many of us may like but which we don't bother contacting the owners because it may be a hassle if there are plenty of domains (and different owners) you like, etc.
But if we can see a list here (instead of those just in the NP marketplaces), we can more likely be able to find names (and owners) who we can start negotiating with. And vice versa.
