This proposed change seems okay. If changes are self explanatory so that no per-function description is needed (e.g. you’re mechanically deploying smart pointers) then it’s okay to omit those. However, I don’t agree with other suggestions made in the same slack thread that the file / function list generation should be optional. I don’t think we should do that. We should encourage people to write per-function comments in commit messages instead. - R.
