I'm not sure the traditional review process is a great fit for this, since the changes are at a prototype stage. Perhaps we might be better served by landing things as they are, as a separate code path guarded behind a cl::opt? This would allow more people to test and contribute patches. Wdyt?

Ping @aprantl regarding this ^^^.

To avoid vagueness: it'd be great if this could be landed as a prototype and then refined / built up from there.
