What do you want Credo to do?

Today the Credo.Check.Readability.AliasAs errors for any use of the :as option on aliases. My problem with that is that there are some module that you don't have control over their names and they're poorly named to not use the :as option.

In my case, specifically the module MyAppWeb.Router.Helpers from Phoenix, if I don't use as: Routes option like the suggested by phoenix generator, we should be using Helpers.page_path(conn, :index), which is a lot less clear than Routes.page_path(conn, :index).

Which existing behaviour would change?

There would not be any backwards incompatible change. The only thing would be that one would be able to set something like {Credo.Check.Readability.AliasAs, ignore: [MyAppWeb.Router.Helpers]} on .credo.exs and all modules on this list would be ignored on this check.
