But do we know if it's still in use in the new app (probably...) ? The libraries were introduced a long time ago and were probably first developed for the iPhone. For this new app they outsourced the effort despite the fact that they acquired Tweetie and hired Brichter. I understand the history of it but my point is I'm not sure this is all still relevant in 2015 especially if Twitter outsourced the effort for this new version. A chromium instance can have fast animations on a mac or windows machine with only web tech (a lot easier to maintain).
