Missing random partitioner in kafka 0.8

[Aniket Bhatnagar]

I am trying to find an implementation of Partitioner trait that supports
for random distribution of messages onto partitions; something that existed
in 0.7 by simply passing null as key. However, the only way to achieve this
seems to be by implementing a custom Partitioner. Is this feature dropped
to discourage use of random partitioning? Have people seen issues with
random partitioning?
