Since the tzdb is 'non-political', common interpretation can be taken as
the rule, and since tzdb is only deemed to be accurate for dates since
1970, information such as the Irish Summer Time Act of 1925 are also out
of scope. As Stephen says, EU law currently applies to the whole of the
EU area, and defines daylight saving ( question perhaps is when did that
apply to Ireland? ) so should there be any timezones other than a single
European time in the tzdb database?

Pre-1970 history still needs a home somewhere and is still as relevant
today as we refer back to pre-1970 times regularly and there IS a
growing archive of legal statutes that document the political decisions
on who that history changed.
