At this time, we have no plans to add in the exp/ labels to our Rancher issues, but we always encourage contributions.
Is there a specific area that you’d like to get involved? We have many subprojects that eventually create Rancher server, so maybe taking a look at those areas would help. One of the easiest ways to get started would be to look at external-dns project.
There are people who are trying to add different DNS providers so that those providers could be used in Rancher.
