So then, what's in a starter that isn't in a modern light fixture now?

How about generally/usually the starter in its entirety in the case of
linear fluorescents of length nominally 2 feet or longer?

Even as far back as the late 1970's, it appeared to me that something
like 97% maybe 99% of 4-foot fluorescents in USA were F40 T12 (1.5
inch diameter) ones in fixtures that had "rapid start" ballasts, 2 "tubes"
per ballast, and no provisions for starters that were not needed for
those.
Electronic ballasts that have since improved upon those (including ones
for T8 [1 inch diameter] "tubes/bulbs") have had a very high rate of not
requiring starters.
