-   We propose adding a new BandwidthStatistics torrc option and consensus
-   parameter, which activates reporting of all these statistics. Currently,
-   the existing statistics are controlled by ExtraInfoStatistics, but we
-   propose using the new BandwidthStatistics option for them as well.
-
-   The default value of this option should be "auto", which checks the
-   consensus parameter. If there is no consensus parameter, the default should
-   be 1. (The existing bandwidth statistics are reported by default.)
+   We believe that collecting IPv6 consumed bandwidth statistics is about as
+   safe as the existing IPv4+IPv6 total consumed bandwidth statistics.
 
-   TODO: Should we collect IPv6 bandwidth statistics on bridges?
-         On bridges, should bandwidth statistics be on or off by default?
-
-         If we do want to collect bridge statistics, and we think it's safe,
-         modify proposals 311 and 312 to allow bridge statistics.
+   See also section 7.5, which adds a BandwidthStatistics torrc option and
+   consensus parameter. BandwidthStatistics is an optional change.
