No, that is likely not true. There are platforms today for which C-based tmux runs but Rust never will. It's not that we are simply waiting for the backport of Rust to magically appear for them, it's quite a certainty that it will basically never appear.

Abstraction happens on the level where tmux requirement is irrelevant. When the usage of Rust gets wider, people start adding support on compiler level for other needs. It is inevitable.
Statistically it is the most fun language there is, based on Stackoverflow. Portability is just a matter of time like with any language.
