I think given that it's the standard and that it seems like it should work, the better question to ask is, "is there a reason to design a whole new protocol to replace it because we think it might not work?" It's possible that trying to revive HNCP and (if necessary) fix it might produce a better outcome, but someone has to want to do that, and I don't see anyone working on it.
