Don't get me wrong, I love rust and use it almost every day. Doing `cargo run` in a project it handles everything is good. This gets lost once you start working in a plugin context. Because now you're not dealing in your neatly organized workplace, you're working across multiple workplaces from different people.

IIRC it's more than just MSRV or even matching version exactly. It also requires flags that were used to compile rustc match (there is an escape hatch tho).
