Is this feature still wanted after being stale for 2 years? Otherwise I could pick this up 😄

First some slimmed-down exercise needs to happen on the Arcus repo's before we can start with new functionality, I would say.

[joachimgoris]

Sure. How can I help? I presume you'd first want to do an analysis?

Yes, working on that here: #578
But first other repo's are prioritized, I believe.

I can also help out in any other repo.

We'll keep that in mind, just now a lot of analyzing needs to happen before we can start creating chore tasks for them. After that has been done, we can definitely some tasks for you!

In other Arcus repo's the good-first-issue label is a good indicator; otherwise, there's a lot of work in adding/defining tasks for the Arcus management team to be done. But we'll it in mind. Thx a lot for the enthusiasm! 💗
