Per https://ask.clojure.org/index.php/11174/deps-edn-specs-from-tools-deps-alpha-are-out-of-date

The tools.deps specs have not been updated with latest changes in deps.edn, particularly:

• New git syntax is not supported, :git/url is optional, added :git/sha, :git/tag

• Specs for coords claim that Maven and local coords can include a :path field.

• No mention of :deps/root or :deps/manifest in coords.

• None of the recent tools stuff is present.

• Missing top-level entries: :mvn/repos, :mvn/local-repo, :tools/usage, :deps/prep-lib.
