Unironically yes. I would love to be done with the endless version churn and would trade many, though not all, features to get it.

So add a couple of vendor repos and jump the versions queue like everyone else. I do this for all my main dependencies... postgres, ruby, etc

Can you give an example?

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

OS should not ship your language run time. OS is a giant cargo ship. It does not turn on a dime and it is not piloted by a "lets rewrite it in rust!" crew.
