e18e now has published https://github.com/e18e/eslint-plugin which includes a ban-dependencies rule that looks like it duplicates this module.
Can you clarify whether this is the case? and where this plugin is heading? Is it deprecated in favor of e18e/eslint-plugin? Will it be maintained? If it becomes superseded by e18e/eslint-plugin, what's the migration path? (how will projects know about it?)
