I'd like to say why not but everything remains to be done, here. Whereas pacman and our toolchain have mature support for multiple architectures, and they have it today. > My point here is that to me it does not really make sense to drop > support for older CPUs. We will have little benefit in newer CPUs. Nothing is being dropped. Every CPU that does not support the new architecture can keep running the x86_64 packages they currently do. > Then automate it?

That would be awesome but the tooling does not yet exist. Personally I do not consider it terribly bothersome to build packages for multiple architectures like we did for i686 and x86_64. And I think it would be preferable to introduce a new architecture tomorrow than wait a few more months in the hope someone implements your proposed scheme. Cheers. -- Gaetan
