I'm astonished.

If this means that macOS accepts "Europe/Kyiv" as a tz-style time zone, but does not support "Europe/Kiev", then this would be a very unusual sort of breaking change, since no tz database version beyond 2022a has been released yet.

Generally, the historic name is preserved with a symbolic link.

Peculiarly, MacOS doesn't use symlinks in zoneinfo but replicates the files,
despite that MacOS freely uses symlinks elsewhere.

The extra storage is inconsequential.  But, still, perhaps Deborah Goldsmith
can relieve my puzzlement.
