I just saw this while looking through the code. this a layering violation, since
content shouldn't know about chrome

 
 using fileapi::FileSystemOptions;
 
 FileSystemOptions CreateBrowserFileSystemOptions(bool is_incognito) {
   std::vector<std::string> additional_allowed_schemes;
   additional_allowed_schemes.push_back(kChromeScheme);
   additional_allowed_schemes.push_back(kExtensionScheme);
   if (CommandLine::ForCurrentProcess()->HasSwitch(
           switches::kAllowFileAccessFromFiles)) {
     additional_allowed_schemes.push_back("file");
