The post my original comment is on discusses doing this at length.
> And have there been any statistics done on that across open-source projects, like mean, median, percentiles and so on?
I am not aware of any. But in all the posts on this topic over the years, codegen always ends up being half the time. It’s why cargo check is built the way it is, and why it’s always faster than a full build. If non-codegen factors were significant with any regularity, you’d be seeing reports of check being super slow compared to build.
