IMHO, I think we're over-..thinking(?) the title. For instance, the same arguments that have been made about the use of the term "privacy" could be done about terms such as "secret" (in "secret key") -- we shouldn't not be able to say "secret key" because it all depends on whether you disclose or publish the key. In this case, theses addresses have the following properties: * They don't leak information about the underlying NIC manufacturer * They don't disclose information about node identity * They don't disclose any information about patterns employed by IPv6 addresses in the local subnet You might use this addresses for incoming connections without affecting the above properties. And you might set up temporary names (and publish the addresses there) without affecting any of some of the above properties. In any case, if you hurt their privacy properties at any other layer, it's a similar case of someone leaking a secret key above (but we still call them "secret"). The best thing a reader of this document can do is read the I-D we're co-authoring with Dave and Alissa. Whatever title we were to chose won't help the reader avoid the ned to do that.
