Before CI became prevalent, I was against checked-in code generation and it took me a while to unprogram that bias and re-evaluate. Its been a big help in keeping runtimes fast with a python program at a previous job and at keeping build-times fast in an open source project of mine [0] I wish there was a simple way in Rust to make proc macros optionally generate code that gets checked in, allowing for most of the macro costs to be shifted to dev-dependencies. While some macros might be generating code for very dynamic parts of applications, others like clap (CLI parser) are less likely to change and could benefit from it.
