I'm a newly licensed glider pilot, and I can't wait to start flying XC. I recently restarted my training after an 8 year hiatus. One of the things that motivated me to get back into soaring is the development of electric sustainers. Having the ability to flip a switch and be confident that the motor will start every time makes XC way less intimidating to me. The risk, and more importantly, the massive hassle of a landout is a real turn-off, personally. I know that I will still have to be prepared for the possibility of a landout even with an e-sustainer, but it seems improbable enough to ease my anxiety about it.

Granted, I don't have a glider with an electric sustainer available to me right now, but after I gain some XC experience with my local club, one may be in my future.

Perhaps if/when electric sustainers become more common in soaring clubs, more people will be willing to fly XC. They may even bring in a new class of people to the sport who would be too afraid to try even local soaring due to the lack of self-propulsion.
