Having been forced to deal with the mess that’s 32-bit arm tunes: Let’s only add an implementation specific tunes *after* having seem conclusive, repeatable benchmark results. 90% of the 32 bit tune files are placebo effect and just explode number of package archs in your distro feed. The goal of aarch64 was to stop being different for the sake of being different, let’s not make a mess because we are used to messes.
