More broadly, different individuals, some representing organizations, have expressed different opinions on what they do or do not want from the tzdb data set. Some would like a full historical record of time zone data, others want stability, many I suspect have absolutely no interest whatsoever in pre-1970 data.
Presumably "stability" here includes "don't convert existing tzdb regions to links merely because they have the same 1970-and-later data" (putting them into the "don't merge" camp); does it also include "don't split existing tzdb regions due to the discovery that different parts of those regions had different pre-1970 data"? (Those who want a full historical record of time zone data would presumably want those existing regions split.)
