If anything, it's helped to clarify that xxxHolic and XXXHolic appear to be the only two names with enough consensus to move to either. It's also shown that twice (atm 8 vs. 4) as many people support xxxHolic over XXXholic, the initially proposed namespace by Cyrus XIII which had 9 supports, and that only one (atm) person supports the current title of ×××HOLiC when there were 7 votes against a move in the previous proposal. I was personally under the belief that more people supported the current title, but the poll has certainly cleared up that notion.
Polls are evil when they try to circumvent discussion, but we've had plenty of that. Don't vote on everything states that "[l]ess consensus exists about votes which regard matters of style, taste and personal preference". This very much seems to be a style issue at this point, as there seems to be few people that think that there is one, and only one, typeset that is "correct" (certainly no one has voted on just one option yet). Since there are multiple "correct" possibilities with near equal weight, the poll is justified.
