I'm trying to think when exactly the GUI was updated. I think somewhere around Vista. You can just check "use all my monitors for the remote session" in the Display tab. I'll admit that with a triple-monitor setup, I've sometimes wanted to remote in with only a dual-screen setup. So it wasn't perfect for me. It certainly did fine for my 95% use-cases. Having to reconnect to adjust desktop size just was never a big deal for me. Maybe adjusting sizes is more of an issue for people today. If I was using a laptop and constantly docking/disconnecting external monitors with a large number of active connections, it'd annoy me to have to completely reconnect each time.
