1) This comment should be updated
2) You should "do the right thing" here w/r/t |profile|

Good catch! Done.

Note that the "received content length" are stored in the local_state pref, so
the existing argument to UpdateContentLengthPrefs is still correct.

   bool with_data_reduction_proxy_enabled =
       ProfileManager::GetActiveUserProfile()->GetPrefs()->GetBoolean(
           data_reduction_proxy::prefs::kDataReductionProxyEnabled);
-#else
-  bool with_data_reduction_proxy_enabled = false;
