Chia-Ping Tsai commented on KAFKA-5246:
---------------------------------------

After eight years, shouldn't we reassess this "backdoor"? The growing number of 
internal topics is enlarging its scope. I suggest filing a KIP to remove it, 
especially since we have specific RPCs available to alter those topics

>  Remove backdoor that allows any client to produce to internal topics

> kafka.admim.AdminUtils defines an ‘AdminClientId' val, which looks to be 
> unused in the code, with the exception of a single use in KafkaAPis.scala in 
> handleProducerRequest, where is looks to allow any client, using the special 
> ‘__admin_client' client id, to append to internal topics.
> This looks like a security risk to me, as it would allow any client to 
> produce either rouge offsets or even a record containing something other than 
> group/offset info.
> Can we remove this please?
