I think the background to this is simplifying the mess of RPM macros which are needed to set all these flags: https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/rawhide/f/macros#_392 https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/ra... https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/rawhide/f/macros#_402 https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/ra... https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/rawhide/f/redhat-hardened-cc1 https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/ra... (and several other places). I'm sure Debian has something similar as do other distros, so having one flag which does it all is an advantage.
