I hope my quick overview has convinced you that coherence is a problem worth solving! If you want to dive deeper, there are tons of great resources online that go into much more detail. I would recommend the rust-orphan-rules repository, which collects all the real-world use cases blocked by the coherence rules. You should also check out Niko Matsakis's blog posts, which cover the many challenges the Rust compiler team has faced trying to relax some of these restrictions. And it is worth noting that the coherence problem is not unique to Rust; it is a well-studied topic in other functional languages like Haskell and Scala as well.
