Month and day names can be spelled out in full or abbreviated in any unambiguous way, this has been documented for ages, Can you provide a pointer to the documentation for this?
The zic(8) man page's FILES section <https://man7.org/linux/man-pages/man8/zic.8.html#FILES> says the following: "Names must be in English and are case insensitive. They appear in several contexts, and include month and weekday names and keywords such as maximum, only, Rolling, and Zone. A name can be abbreviated by omitting all but an initial prefix; any abbreviation must be unambiguous in context." Wording about names and abbreviations has been present in the TZDB documentation, in some form or another, since release 2010j. To help avoid further confusion in this matter, I recently installed the following patch to give examples of month names and abbreviations, and this patch should appear in the next release: https://github.com/eggert/tz/commit/96fa7b7dd4cf8bd415a50e0f6a190488fa3c8078
