It should also be mentioned that there are a bunch of ways to improve compile times. Bevy for example has a feature to compile itself as a dylib, which helps avoiding the cost of relinking everything together. The Cranelift backend for rustc will also help reducing compile times in debug mode. In Bevy's case it could be used for the binary crate only, leaving Bevy itself and other dependencies built with optimizations and dynamically linked, while the binary crate gets rebuilt very quickly but with less optimizations. Hot reloading still has a place for quickly prototyping thanks to not resetting the state of the running program, but this is a lot trickier to do with Rust. I think we'll likely see better scripting support (with hot reload for the scripts) instead.
