This issue seems to be asking for 2 features, topic reviews and cross project dependencies. Gerrit already supports dependent changes. Gerrit also allows you to apply topics to changes thereby allowing you to group/classify a set of changes. I believe this satisfies the topic review feature. Gerrit does not support cross project dependencies though. Maybe we should close this issue?
