I don't agree that it's a good idea to have to have the server query some massive device database in order to find out what the requesting device does and does not support. Device databases are, by their nature, going to be hard to maintain, hard to support, and not tell us all we need to know. How is a device database going to tell us the current connection speed, or the user's zoom level, or device orientation, or anything else dynamic that may be relevant to know on the server? The database route is merely an extension of UA sniffing, which was about detecting devices and assuming capabilities and settings. The problem with that was inaccuracy, and ongoing laboured maintenance. I want us to detect the actual capabilities directly - exactly how CSS works. Detect what's there. Skip the middle-man. How does it make sense to resort to siloing this information in a database, when we're the body that makes the standards that would allow direct knowledge? I'm less interested in current work-arounds (and that's what those are, workarounds and best guesses destined to fail at some point) and more interested in getting accurate, reliable, future-proof data exposed.
