Yes, I was definitely thinking of the comments. Also, the ordering of
Zones (which is irrelevant). Stuff like that. The idea is that the
generated TZif files should be identical to what they would have been
without the alike-since-1970 patch. I would expect similar results in
downstream systems that don't use TZif.

How about this: we could say that we won't do any sort of merging like
this in the future. In other words, this is the last time we'll be
merging legacy zones because they differ only before 1970. Would a
statement like that help? We could put such a statement into the NEWS

Sure, but no matter what we do we'll be making a political statement.
The statement I'd like to see is "let's avoid political data when we
can". Admittedly not everyone agrees (which is also politics :-).
