In the short term, I think that the tz project should stick to the 
existing practice of using 1970 as a cutoff date.

In the long term, think that the tz project should attempt to 
provide as much high-quality data as is reasonably feasible, and 
that users of the tz data should have the ability to "winnow" and 
install only a subset of the data.  Here, users of the tz data 
includes OS vendors, appliance vendors, other software projects, 
software packagers, system administrators, and end users.
