Does the existing TZ database want to make provision to handle the results if people are prepared to put in the work needed?
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.
