Guozhang Wang commented on KAFKA-13588:
---------------------------------------
With 4.0 on the horizon, we can now finally consider removing the deprecated
`init(context, root)` in that release, and after that we can consolidate these
funcations. I'm reassigning the assignor so that anyone can take it. My
suggestion would be: either anyone taking the PR to remove the deprecated
`init` function can clean this along side with the PR, or someone else can do
it after the PR for removing `init` is merged and if we have time still to make
the 4.0 deadline. Otherwise, it can go in 4.1
> We should consolidate `changelogFor` methods to simplify the generation of
> internal topic names

> Or any other place that we generate an internal topic name.
