It looks a lot more fun to use than C, but it seems like any application that couldn't use C++ or Rust due to some project policy or something, probably could't use this either, and I'd generally take C++ over C any time if available.
Maybe I'd try it on a platform that had no C++ support?
I've been eyeing this project for quite a while now, but as mentioned in its FAQs, I usually get scared off by the idea of pulling in a large dependency.
If anyone's made the leap to use it in a project, I'd love to hear about your experience.
