I wonder what this means for older versions of Messenger? Facebook talks about rewriting their server logic to support all the removed code from the mobile interface, but does this mean that we will soon see support for < iOS 10 (which Messenger does not support for new versions, as far as I ma aware) be dropped? It's pretty sad that a Messaging app can't be run on a perfectly fine nine year old device. Bring back IRC :)
