I only know of two cases where a timezone with data was
converted to a link and the data never reappeared:
America/Santa_Isabel on 2016-01-27 (2016a)
Pacific/Yap on 2005-08-22 (2005l)
Some timezones such as Asia/Ishigaki were in tzdb for a very
short time and then were dropped without trace (1999b).
