Comment 6 for bug 1972043

doko can you please provide more details on why you think this should be done in dpkg instead of gcc (as we have done for almost all the other hardening options)? As Kees says, adding it to gcc means not only does this benefit Ubuntu archive packages, but also any software which is built on a Ubuntu machine using gcc (ie snaps built by launchpad, packages built on Github using Ubuntu as the CI backend etc) - which is a great benefit IMO.

What advantages do you see in adding this to dpkg rather than gcc?
