Not trying to get in the middle of the arugment here, but there are requests in the UserVoice site with 27,307 votes right now.  The only objective measure here is how many votes a request has, because that's the only variable none of us control except the user base.  Since there are items with more than 25k votes, it's not unreasonable to say that an item with 4 votesis not a popular request.  If the top voted item only had 10 votes it would be a laughable argument, but the gap there is pretty big in my opinion.
