I think, from observation, that the Rust project has worse burnout problems than most other similarly-sized open source projects. I'm not sure whether it's more to do with the way the project is organised, the state of the codebase, or the sort of person that's attracted to working on Rust in the first place.
Maybe it's because Rust is new and well designed. People who have adopted it probably care about this and want to maintain it and that's hard. Maybe it's my perfectionism, my desire to build and live in an ivory tower, but I feel this as a Rust user, a fear that they might break some perceived perfection that I care about. I've commented before that "at least C++ developers are free from the burden of using a perfect…
Also as a generic tool I think it ought to support multiple paradigms and it does not. Just because they (language designers) believe that doing thing their way is superior to what others might find more appropriate does not make them right.
Personally - I would use Rust if clients insists which so far has never been the case, otherwise I would take a subset of C++ any time over.
