We were using this information as it has been a vivid part of the
TZ data one and half a decade ago as a signed save_secs field to
be added to signed utf_offsec . The information is still in
there; i am not ._.; otherwise an official statement on that data
i would appreciate, too.
What would be an issue to me is instead that TZDIST doesn't offer
a binary representation but only (iCalendar,) JSON and XML, which
require parser libraries, whereas with CBOR the IETF standardizes
a wonderful, extensible and otherwise future-proof binary format
that also has been designed with easy JSON mapping in my mind.
And especially the more simple JSON/xy libraries read anything
into memory before text parsing starts. Just my one cent.
