Interesting suggestion, though AFAIK that typically relies on auxiliary onsite power source at some generating plants, as noted in the Wikipedia article intro?
Anything you can find to support grid interconnects as black-start capacity?
Purely speculation based on the small capacity compared to total generated capacity.
From what I understand there can be a number of different techniques for black starting a grid, including pumped storage / hydro generation because they can be started with very modest power. Being able to jumpstart a grid based off of a neighbouring grid seems to make sense.
