 We separate `AppContextProvidersSearch` and `AppContextProviders` because we don't want to trigger `AppContextProviders` implicit generation during implicit search outside of service instance generation.
   Note that Scala currently has no way to make a macro that generates a given instance to fail an implicit search silently. We can only make errors during the search, which will abandon the whole compilation.
