Privacy is not really an issue here. Firstly we're talking about devices, not people. More important, we're talking about ULA addresses that will not be visible outside the domain covered by the ACP. So the old-fashioned technique of using modified EUI-64 would be safe, and there is no real need to use RFC7217. However, since RFC8064 recommends RFC7217 for all SLAAC nodes, and the ACP uses SLAAC, RFC7217 is automatically recommended by the existing standards. I don't think we should mention EUI-64.
