As for the dub-registry i can only advice to avoid having it do 
more things than it already does.

In fact, I can only suggest to make it considerably dumber.

Right now it partakes in dependency resolution by recursively 
resolving transitive dependencies. This has considerable resource 
requirements due to the reconstruction of relative big json 
snippets.

This thrashes a lot of memory and puts unnecessary pressure on 
the GC, resulting in high memory requirements for a relatively 
simple registry.

The tradeoff is having the client make multiple requests, 
however, they can be done semi-parallel and, without requiring 
transformations, can be streamed straight out of the database.
