As the type's minmax_multi opclasses are marked as default, I believe
it makes sense to explicitly mention that only indexes that use the
type's minmax_multi opclasses would need to be reindexed for them to
see improved performance. The types' *_bloom and *_minmax opclasses
were not affected and therefore do not need to be reindexed.
