While Github added a lovely thumbs-up voting button, it says explicitly in the projects documentation that '+1' comments should be used to support a feature. Further, it's apparent that those comments are being automatically counted and shown here: http://caniuse.com/issue-list/
If you want to show your support for this issue, please use the old +1 comments.
