I'm concerned that using CHANNEL_UNKNOWN will mean that people building their
own copy will have this on by default, which while not a disaster, I think will
violate the principle of least astonishment in that case.  Maybe just make
kForceChannel always CANARY and put the kForceChannel check behind an #if
!defined()?

 #else
         chrome::VersionInfo::Channel kForceChannel =
             chrome::VersionInfo::CHANNEL_CANARY;
 #endif
         std::string group =
             base::FieldTrialList::FindFullName("AutoReloadExperiment");
         if (channel <= kForceChannel || group == "Enabled")
           command_line->AppendSwitch(switches::kEnableOfflineAutoReload);
       }
     }
