Hello to you all,

Question:  Is there a point to adding IPv6 addresses to the ORPorts of my bridges?

BridgeDB has an IPv6 option:
https://bridges.torproject.org/options

But there seems to be a bug right now:
https://trac.torproject.org/projects/tor/ticket/26542

Will they then operate somewhat in the fashion of guards without published metrics?

They will appear on Relay Search under the hash of their fingerprint.
(That is, SHA1(SHA1(RSA Key)).)
