Review Comment:
I know for sure we skip empty lists and don't send requests for all the
partition offsets related events (on the `OffsetsRequestManager` on
[fetchOffsets](https://github.com/apache/kafka/blob/cdf726fd358f9be3438ceefb01073ab40a31a8b4/clients/src/main/java/org/apache/kafka/clients/consumer/internals/OffsetsRequestManager.java#L151),

and
[validatePositions](https://github.com/apache/kafka/blob/cdf726fd358f9be3438ceefb01073ab40a31a8b4/clients/src/main/java/org/apache/kafka/clients/consumer/internals/OffsetsRequestManager.java#L216)).
That being said, here is about fetching the committed offsets, and I don't
see a clear early return but maybe I'm missing how it happens so let's wait for
@philipnee to give it a closer look.
