what is the proper way to retrieve Monticello repositories?

I've always simply queried the system for instances... e.g.��MCSmalltalkhubRepository allInstances detect:

But is there some manager or something? (Akin to RPackageOrganizer default)

Also it's interesting that both Pharo50 and Pharo50Inbox are MCHttpRepository instances and not��MCSmalltalkhubRepository.

Thanks,

Peter
