This only makes sense if you can show a noticeable performance
improvement using one of the those -march options with at least one
benchmark from those which we have now in the kernel.

And even that use case is limited because the majority of the kernel
builds out there are distro kernels built with -mtune=generic so it
would only make difference for people building their own kernels, who
are a small minority, relatively.

Thanks.
