Review Comment:
   I don't think this is correct. We should only update 
`registeredServicesByName` right where `registeredServices` is updated, so they 
are always in sync.

Review Comment:
   Missing javadoc (build will fail).
   Let's mention that this map simply improves lookup by name and should be
