We are certainly interested in corrections to the
existing pre-1970 data.  We've accepted those in
the past and it shouldn't be too much work
to maintain that data.

If we're talking about adding the thousands of new zones
that would be needed to support pre-1970 standard and
daylight saving time, I'm not sure this list would be
a good place to discuss each and every datum individually,
though we could well be interested in incorporating
the resulting batch of data as an optional extension
to what we have now.  We're currently thinking about
possible ways to support such an extension, with
Zefram's code being the most recent proposal.
