We use a build that exports multiple cache manifests, for different devices/platforms. Something like:

plugins: [
  new AppCachePlugin({
    exclude: [/ios/],
    name: "android.appcache"
  }),

  new AppCachePlugin({
    exclude: [/android/],
    name: "ios.appcache"
  })
]

Problem is, that produces an iOS appcache that includes the android appcache! I can't think of any reason why anyone would want to cache the appcache, and in fact that can lead to an impossible-to-update application.

Should we automatically exclude /\/\.appcache$/ files?
