How I imagine changing that looks:

Maybe, honestly I don't know. But I know the server was built with only mobile users in mind, and thus
a lot of scripts are only checking for mobile/facebook platforms and other oddities. There may also be other weird things that need to be looked into, such as identifying vs traditional accounts.
And more importantly, there is probably lack of motivation to put it as a higher priority. It wouldn't really bring in many more users, and probably wouldn't move that many users to the client.
