The dynamic linker already has the `glibc-hwcaps` mechanism to load optimized implementations of ''shared objects'' [3]. This means that packages can provide optimized libraries and they linker will be automatically load them from separate directories if appropriate. (For AMD64, this is `/usr/lib64/glibc-hwcaps/x86-64-v{2,3,4}/`.)
Is this something specific to x86_64 that the libs needs to be nested in a place such as `/usr/lib64/glibc-hwcaps/x86-64-v{2,3,4}/`? Why not use e.g. `/usr/x86-64-v{2,3,4}/lib` directories instead? Or something more universal.
Adding directories to the /usr sub-space generally gets bogged down into 'You are polluting my name-space' arguments which get no-where because some of the people getting angry is having to live with some 3rd party rules and regulations which stipulated how things look and will only get updated once a decade or so. [The same goes with subdirectories in /usr/bin etc where it causes similar problems.] There tends to be no 'general' case which works unless it gets 'agreed' upon by some outside of the distro body that publishes 'versioned' standards.
