There is a use case to change them back to the introduction of daylight
saving time if it is judged that that that has been the preferred
abbreviation since that time.
For the same reasons as going forward, a tool (such as a calendar) which
reports past daylight saving time events remains ambigious for past
dates if the abbreviations are not put into the database retroactively.
I don't think its the responsibility of tz to report what tz did in the
past - but to represent what was in common use in the past.
