Hi Bob, I prefer B. I think there is interest and possible need for an alternate solution and it seems reasonable to depreciate site-locals (which are already supported to some extent in some running code) after we have a replacement for them. I fear that if we do not do this, there may be motivation for people to start to deploy something which is targeted as a replacement for site-locals but has no IETF documentation behind it.
