This concept of upstream and libre.sh operators enables us to build nice and reusable code upstream and also have a really tailored operator for our libre.sh needs.
Once the 2 levels are built, it is not difficult to add a UI on top of it.
You might also be frustrated by this need of 2 level operators, there must be a better solution for it. We do think so too, but it is a long term goal that we have to work with the kubernetes community.
