Sure! Basically, you'd write a post in https://discourse.llvm.org/ with a title along the lines of `[RFC]; stop using PWD in current_path` and some explanation of what you'd like to change, why, and what the impacts are. Folks will leave comments in the post about things you should also consider, and eventually discussion dies down and we (hopefully) have clear direction on what to do from there.

I would recommend posting this RFC in the [Clang category](https://discourse.llvm.org/c/clang/6) though it's possible the changes could impact other projects.
