I think this was a bug. `repartitionForJoin` actually ignored the `otherValueSerde` and only used the `valueSerde`. In this case, we would use the incorrect serde to de/serialize the repartition topic.
I've clarified it by adding the correct generic type parameters and expanding the argument list of `repartitionForJoin` to only take the information it will actually use.
