Indeed, the screenshot is convincing. Not so the maintenance state 🤕 which is very important.

We as in "OpenCloud" would be very willing to engage with maintenance of such an important component, if

• it is a very good solution
• there is no other, maintained solution out there

But, unfortunately it feels a bit early for us to jump on these kind of activities. We need to concentrate on the core first, and build a solid foundation both technically and economically.

That does not mean that it can not be worked on this already, eg. by evaluating the solution (or watch out for another one), building a POC and such.
