Actually we learned about Google's NCL way after, when discussing with CUE's author, that we happen to know as well. So it's a funny coincidence. Nickel originated from NCL which is both a recursive acronym (Nickel Configuration Language), but also came from the ambition of improving Nix: it also meant, at least initially, Nix Configuration Language, I believe. Maybe there's been a wordplay around Nickel <-> cheap configuration language as well. We also co-organize CONFLANG (https://2023.splashcon.org/home/conflang-2023 https://2023.splashcon.org/home/conflang-2023) with CUE's author and other people, and we got several subscriptions and talks from Google last year. This is available here: https://www.youtube.com/watch?v=NbEkN8OOQFQ&t=23367s https://www.youtube.com/watch?v=NbEkN8OOQFQ&t=23367s. I you look at the first comment, all talks are indexed, and there is in particular an experience report on improving GCL incrementally without breaking anything at Google (https://www.youtube.com/watch?v=NbEkN8OOQFQ&t=23367s https://www.youtube.com/watch?v=NbEkN8OOQFQ&t=23367s). Very interesting!
