It is definitely just as useful to have negative feedback as well as positive. However, your comment could have been a lot more useful had it been more constructive.
For example, just saying that you see no need for it isn't enough to be helpful. You could be an eskimo with no map coverage, in which case of course it's not useful. What would have been useful is explaining WHY it's not useful to you, or more specifically what your current workflow is that this is not better than.
But you're right, no one benefits from a loop of "great idea"... which seems to be the only feedback you get most of the time.
So in case this is still going... I don't see any great need for this in my life because I don't share addresses in this fashion. I type out the address in an email or give it over the phone or in a text message. 90% of the time, in a text message as it is my primary means of communication with people who I would need to share a physical address with.
