Re: Update on adding additional x86_64-vX subarchitecture leves via glibc hwcaps

I maintain the nodejs-electron package. I guess it could benefit from a v2/v3 build, which the hwcaps solution would not allow. This software's upstream claims that merely allowing SSE3 (which isn't even x86-64-v2) produces a significant speed boost and have dropped support for baseline x86-64 in their official builds.
