Well, the poll was closed with 80% support. It probably should have been extended, if for no other reasons than that votes continued to come in at a pretty good clip and there is no pressing reason to close it on deadline.
If I were a developer or a WMF executive, I might pause at implementing a proposal for quite significant change on the English Wikipedia based on a poll with only 320 participants.
