A Processing Group would serve as a reusable unit, which then has version
control applied to it. You would model your flows to abstract interactions
with e.g. in/output port objects.

They also mentioned that nested PG can be versioned separately, looks like
git submodules behavior, but I haven't tried multi-level versioned PGs yet.
