I think the changes make sense but I also worry about what the fallout from the changes will be; has anyone tried rebuilding a distro worth of packages to see what the impacts are here? I'd like to think they're minimal, but changing how warnings turn into errors or are suppressed strikes me as requiring a higher bar for verification before we backport.
