It mainly has to do with familiarity with the framework. The focus of the work was on the collaborative server bits, not learning a new framework/ecosystem and I feel very comfortable in PubSweet, being its lead dev. The project also served as an app-building exercise, as we’re just now meeting in Cambridge to focus on that aspect and reusable components within PubSweet. And when all said and done, there weren’t any friction points with this approach, it all just sort of worked, from data model migrations to React frontend, so yay :) Hope that clears it up!
