I disagree... and unless you polled the customers about this particular issue blanket statements about importance aren't really valid. You see this as purely aesthetic - but if that was a fact half of the descriptions in Who's Online would be missing because nobody would bother with them. Where exactly are you doing all this mass polling of people what they want?
Showing "Unknown Location" location in Who's Online screams "someone has yet to fully integrate this mod" to anyone who bothers looking - it looks unprofessional. And debating whether it should be included or not is like debating whether a major feature should come with documentation or not. It's simply redundant discussion. There are things that just have to be there for the sake of completion, professional look and, not lastly, because they serve a function.
Now, certainly, you may not care about any of these things but they're still a fact nonetheless. Putting this up for discussion is like putting including help for discussion. Most people don't need it and/or don't read it, especially not those people who'd vote in your poll. Following that logic, we can simply skip including help for the minority that needs it. Not quite?
