Regarding feedback on the tooling I think it’s a great step forward. We have a fairly complex setup (here’s @plexus describing some of our issues we ran into).
It now looks like we’ll be able to migrate to tools.deps, test-runner, cljs.main and pack. We’ll keep a project.clj around to install datomic using lein until there’s a built-in solution for authentication (see TDEPS-9) but I think it’s looking very promising. Will keep you posted about our progress. Thanks a lot for your great work on it @alexmiller!
