Support multiple superuser addresses in Ownable

[stefann-01]

Extend Ownable to supports two superuser addresses (main and backup). This would allow users to recover contracts if the main address is lost while keeping the simplicity of the existing design for those who don’t need this feature. The Authorizable extension allows multiple addresses but still relies on a single superuser, which doesn’t fully address this issue.

I’m interested in working on this but would first appreciate hearing some thoughts.

Yes. I ran into a similar issue, and it is why I built mgroup for my config realm .

I'd love to collaborate on this as well. I made some design choices for mgroup (short for Managed Group) that work for what I needed, but I think it could be generalized. What I wanted was:

• Primary Owner - Can and Add backup Owners and members
• Backup Owners (Backup Owners can ClaimOwnership() to become the Primary Owner
• Members are like what's in Authorizable, but it has a few features like paginated listing of members, etc.
