So, the question: Any suggestions on how to filter timezones within
each country to drop those that as of today are not relevant except
for historical differences?
Use zonenow.tab rather than zone{,1970}.tab.
The last line of each timezone definition appears to contain the current
POSIX definition. (I don't know where this is documented.)
"Version 2 format" in tzfile(5)
If those lines are identical, might zones be merged?
That could be one possible approach, but would need to be checked.
Another might be to compare all tzdata fields.
