Sure. In the Rust ecosystem, if you submit a pull request to a library it is very common for the maintainer to release a new version soon after. Even patches to the Rust compiler repository are released to stable in a matter of a few months (and the very next day for the nightly channel that many people use)

There's always workarounds and so forth, but it is really empowering to be able to have an impact over such a short timespan
