Thanks for bringing this up, Stephan. I am +1 on dropping support for Kafka 0.8. It is a pretty old version and I don't think there are many users on that version now.
However, for Kafka 0.9, I think there are still quite some users on that version. It might be better to keep it a little longer. Given that dropping connector support is a backwards incompatible change, technically speaking we need to bump up the major version. I am not sure if release 1.10 is a good version to remove the code. Personally I prefer to mark Kafka 0.8 connector as deprecated and remove the code base in Flink 2.x.
