Yes, were in the process of making some design decisions -- I'm also in Roma for the CLA Summit and am presenting tomorrow...
One thing that we're evaluating is the impact of changing the process VI to be Dynamic Dispatch (with the ability to call or override the parent). This changes slightly the mechanics of process registration and synchronization.
Additionally, we're working on a full scripting API to allow programmatic creating, editing, and inspection of JKI SMO classes. This aims to enable creating user interface tools that simplify development.
We've been doing this experimental development outside of GitHub to avoid a lot of noise. I'd be happy to loop you into what we're working toward and some of the open design questions.
