In my original email I tried to distinguish between the TZDB ID name
(which of course doesn't have to be translated), and the names that are
actually presented to the user when they select a time zone for their
system, or add a calendar event with a time for a specific zone. The
latter should be localized, IMO.

Agreed. I wanted to point out that either the "primary" local time may
be kept unchanged if the rules for that zone change in the mean time,
and the derived times for participant will change, or vice versa. This
depends on the kind of event, and many people I know are not aware of
