In Elixir land, the Ash Framework created a package called usage_rules[0] as an experimental attempt to solve this problem a few months ago. The latest version of the Phoenix Framework (1.8) includes it in their `mix phx.new` generator and in their own hex packages[1]. Library owners would need to add their own usage rules, but it seems to help even for just the core packages Phoenix includes.
