Yes, it would be possible!

And, in fact, it looks to be quite a simple task.
There is an old branch admin-client in this repo where I started implementing it and made create and delete topics possible. Adding other functions should not be problematic.

I just rebased this branch in case if you (or anyone) wants to have a look or maybe even take over. It doesn't currently compile because we changed String to Text in a couple of places, but it should be a very easy fix...

What is the status on the Admin client? Is there somebody looking into this?

Hi, no, not really.
I had a start in the admin-client branch at some point in the past, but didn't end up merging it because I didn't really need it myself.

Too bad, I was looking to start a little project using this library to learn Haskell, but I would need the adminClient for that.

@AlexeyRaga, I will look into the current code and give it a try to implement it myself
