There is consensus amongst the ARM distro team that this should be turned on for arm64. Our preference is to turn it on for the 32-bit arm arches too. However Ubuntu chose not to enable this on armhf in 2019 after a rebuild test (although it doesn't look significantly worse than arm64 to me on that chart - needs more detailed investigation). We will do some new archive rebuilds to see what the current status is. https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20190614-eoan.html I've also asked the arm compiler team if there are any known issues with this feature.
