For historical dates, I'd rather everyone knew how to convert accurately to and from UTC (2 conversions), rather than relying on everyone to have a bug-free and up to date implementation of 2N(N-1) conversions.

That said, the exception for local time, at least in my opinion, is agreeing on dates in the future meant for human interaction (e.g. "I'll meet you at 7 AM local time in Time Square on the 3rd of April 2068"). Here time zone rules may actually change before the date transpires, and you can't be sure of the representation in any other zone or format until closer to the event.
