> Yet they do pay off in Rust because of my favourite Rust feature: the ability to refactor large-scale software without breaking anything

I think crater also deserves some credit here - given how much Rust source is in Cargo, it's very useful to be able to run a refactored compiler against all those packages and see which don't compile or start failing their unit tests.
