It's irresponsible to break iOS specific content or iOS applications like that. Think of end users who have been using an app suddenly faced with an erroneous behavior in new version of iOS.

I don't follow. They specify user-select and -webkit-user-select. If -webkit-user-select preserved the old behavior, then it would work precisely because it also specify user-select, which overrides the behavior of the prefixed version.
