I agree with the significance. I've liked the additions over the past few years of course, but the last time I felt a release was this significant was async, I believe 1.39, about 3 years ago. And coincidentally, the times I've wanted to reach for GATs have been when dealing with Futures (specifically dealing with lifetimes of Futures produced by Fns; basically what gates async functions in traits). I'm excited to be able to finally use them in my APIs!
