> Just for laughs, Java seems to have its own TZDB

Well, there is also Joda time and icu4j that have their own TZDB which caused me one very stressful day until we found this fact.

To the original point, then there’s people like me that spend time actively ripping out “vendored” copies of tzdb in OSS libs to make them instead use “the one true copy” that is itself painstakingly kept accurate everywhere. Then add the extra time required to update those patches when new versions are released... Copying/vendoring dependencies like that is a great shortcut for a project but creates a huge hassle in large systems (a single OS counts, thousands of packages).
