At some point with something like Apple Maps there were always going to be edge conditions where it would be bad, the problem is just too vast. And at some point you have to pull the trigger so that the developers stop trying to mitigate whatever they can think of and start fixing problems that users actually have. Those two things are never the same thing (which is really the trouble that things like "minimum viable product" and "YAGNI" are trying to get at). At some point you need to draw a line in the sand and figure that it is good enough to ship, then you generally get blindsided by a bunch of issues you never dreamed of and then all your priorities shift.
