I have seen a lot of these co-ordinate based alternative address mechanisms (in fact the author gives a list -- https://github.com/roberdam/Xaddress#compare-encodings). But in my opinion, one thing they all ignore or get wrong is establishing some kind of linking mechanism between real world and co-ordinate based addresses. This is a hard problem, but one without which it is not going to be able to gain significant adoption.
How do we solve it? I am not sure. Maybe somehow augmenting regular national postcodes with coordinates would work better than these (kinda like the 4-digit augmentation to US ZIP codes) – because those are things you use on a daily or atleast monthly basis, and remember. Something like 98002-MAGICAL PEARL would be more easily remembered, and not get rid of existing information.
