The lang team would be in charge of these kinds of features, and I'm not on it, so I can't totally say. There are certainly members who do want this stuff. However, community sentiment is all over the map. https://www.reddit.com/r/rust/comments/b6bu2c/idiomatic_mona... is the reddit thread on this post, you can see a number of different opinions expressed there.
I personally want to see examples of real Rust code that has a problem that this solves. I get monads, I like monads in Haskell, but I'm unconvinced that the additional complexity is worth it in Rust.
