whoever is telling you this is simply wrong. some people may like positional accuracy to be included with coordinates, but frankly, i think many of those people misunderstand what that information means because they have no idea how it is collected.
if someone is actually using the word “useless” to describe your observations, i think it may be worth writing back to them that they are just wrong and to stop misinforming others. if i got a message like that, i would almost even consider flagging that person’s note as abusive to further discourage them from doing this to others.
