docs: Creates a site switcher that redirects to a <code>.mobi</code> domain for normal site requests that either
  originate from a mobile device or indicate a mobile site preference.
  Will strip off the trailing domain name when building the mobile domain
  e.g. "app.com" will become "app.mobi" (the .com will be stripped).
  Uses a {@link CookieSitePreferenceRepository} that saves a cookie that is shared between the two domains.
