Are zap stoppers really needed on alternators?

provide protection?

By limiting voltage. Diodes can tolerate massive current for short
(milli or microsecond) periods of time without damage from overheating,
but excess voltage spikes of the same duration may "zap" the crystal
matricies that make them work as diodes.
