I would find it astonishing too, if that was what was being suggested. But it's
not. I'm merely suggesting standard practice that is commonly done by other tzdb

This currently contains a copy of tzdata 2018c, along with a small patch that
supplies some time zone links (e.g., SystemV/AST4ADT) that were removed from
tzdata in release 2005p, links that Debian kept due to compatibility concerns.
This is not a fork of the project in any real sense; it's just routine shimming.

accommodate that disagreement, and a similar approach would work well here too.
After all, it's simply not practical to insist on complete lock-step agreement
among all tzdata consumers.
