Well, I've seen the effort needed in the past to lay the foundations (when working on SHR and FSO) and see what's needed now (when working on PureOS). The difference is massive - turns out that thanks to things like always-connected 2-in-1 laptops with mobile broadbands and hidpi touchscreens, lots of things that you simply had to make "mobile specific" in the past can be just reused from the desktop now; and improving them makes things better for all GNU/Linux users, not just mobile ones. The telephony middleware is a great example of that - it uses ModemManager, which is a part of a regular desktop stack and already well-integrated in GNOME (and other DEs) for many years. Thanks to that, you can just plug a USB 3G/4G stick to your laptop, install Chatty and start SMSing - just like that, plug'n'play (you may even be able to make calls if your modem exports audio over USB, but it's rare).
