https://www.scala-lang.org/blog/2016/11/28/spp.html is probably what you would call the Scala folks' attempt at this.

That said, it seems more common in Rust for there to be a consensus about which library to use. Perhaps this is simply due to its age? I've seen a few libraries recommend you migrate to others because the pace of Rust conceptual evolution made the first library outdated in short order This is somewhat less so now, though very recent features like custom derive and even impl Trait can affect dramatically the aesthetics of a library and how someone chooses to implement it.
