Similarly related, no longer being able to tell iPad OS and macOS apart server side was a major blow for us. We have essentially “continue this in the app” buttons whose existence and how they passed state (iOS vs Android) was determined server side. We rewrote that all to happen client side because you can check “is it a Mac?” && “does it have multi-touch support?” And know it’s an iPad - at least until they build a touchscreen Mac.
