What would actually be interesting to me is info on how local data protection authorities across the EU are now interpreting the principles articulated by the ECJ when applied to standard contractual clauses which are what most data transfers actually happen under rather than Privacy Shield.
How all this will play out and be interpreted by regulators is interesting and currently hard to see how everything will be reconciled between trade in digital services, the US national security state, and the fundemental rights guaranteed to EU citizens.
