Google's Gary Illyes said on Twitter this morning that you can prepare for the mobile-first index which likely isn't launching until next year by looking for noindex directives and faulty redirects.

The n1 redirects are the same thing as faulty redirects as described here and over here.
Truth is, any SEO who works on a site already does this, so this isn't really new.
