Ah I see. My personal take is that while Rust introduces some inconveniences not present in those languages, those languages also have plenty of inconveniences that are not present in Rust. From my perspective, enums and traits are so much better than classes as abstractions that most of the productivity lost is already made back.
Rust is a very well designed language no doubt, but I think maintenance is where high level languages have an upper hand in some domains.
Also, there are plenty of high level languages with traits, eg Haskell, but if you prefer one where it is easier to express things optionally with an imperative/OOP mindset, Scala.
