Nice! As for next steps, what about using Wiktionary as next "pioneering project" for the new CirrusSearch (first opt-in and then default)? It exists in most languages (we really need to see how the new search works in different languages), it's one of the most impacted projects by the new features (e.g. expanded templates indexing) and at the same time allows to make full-project deploys without impacting some 95 % of our traffic.
