+1 Thanks for the graphs.

I took a look at it. There are some modules - oslo.cache, for example
- which status should be updated - I don't think we'll need that
memorycache module anymore once [0] lands.

In the dependencies diagrams, it looks like oslo.policy does not
depend on anything. However, it should depend on oslo.text, oslo.log
and oslo.utils. I'll update the graduation statys wiki.

Should we have a meeting after i-2 cut? I think we could go through
the list again very quickly.
