 bridge stats would be useful. (I'd say "like the existing bridge stats",
 or "like the IPv6 relay stats", but I'd only be guessing.)

 Hi! I believe the BridgeAuth doesn't do IPv6 reachability checks, and it
 does '''not''' set `AuthDirHasIPv6Connectivity 1` (cf. #24262). We don't
 have bandwidth checks at all for bridges right now, but we should have
 them soon. (I don't know yet when we'll have IPv6 bandwidth checks,
 perhaps this is a good task for the next IPv6 hackathon?)

 The bridge graph above is good since if/when `AuthDirHasIPv6Connectivity
 1` is enabled on the BridgeAuth we'll see if it hits any bugs with
 accidentally (or purposefully, it's difficult to tell if there's only one
 BridgeAuth) excluding large numbers of bridges. I'd be curious to see how
 many of each transport are offered on IPv6 addresses, since (sorry, bad
 data from kludgily grepping the BridgeDB logfiles…) there's extremely few
 requests for IPv6 bridges. I believe that dgoulet's bridge is the only
 bridge to offer an IPv6 pluggable transport, but I haven't checked in a
 while.

 That's all I can think of for now… hopefully that helps and I'll let you
 know if there are any other graphs which would be helpful.
