I don't see this is a fact that the TZ DB cares about, e.g. I see no
evidence the code SET had been in use for time in Sweden:


1:00:14    SET           Swedish (1879-1899)*

Changing abbreviations on a year basis requires much more research.

Yearly adjusted : people need more time to decode an acronym

Not-yearly adjusted: people understand acronyms for past times as they
do for current.
