Lianet Magrans commented on KAFKA-18767:
----------------------------------------

I think you have a good point! I was just working on the reconciliation path, 
and landed on this exact area this morning (related to the auto.commit). The 
config seems to be allowed, which is confusing (even though in practice there 
is no CommitReqMgr in place to auto-commit, and the ShareMembershipMgr does not 
auto-commit either before revocation simply because it takes no action on the 
hook for it, signalReconciliationStarted)

> {{share.auto.offset.reset}} 
>  * {{enable.auto.commit}}  and {{auto.commit.interval.ms}} : share groups do 
> not support auto-commit
>  * {{group.instance.id}} : this concept is not supported by share groups
>  * {{isolation.level}} : this is handled by a dynamic group configuration 
> {{share.isolation.level}} 
>  * {{partition.assignment.strategy}} : share groups do not support 
> client-side partition assignors
>  * {{interceptor.classes}} : interceptors are not supported
>  * {{protocol.type}} : this configuration is used to select the group 
> protocol used for KafkaConsumer
>  * {{session.timeout.ms}} : this is deprecated in KIP-848 and is not
