The 'Frontend" should also be something that can be added/removed from Plans; as it's something you could upsell or use to encourage users to upgrade to higher plans.

QUESTION: If the SaaS version is hosted on a subdomain (e.g., app.domain.com) would the ''Frontend'' feature for customers still work as part of the main domain? E.g., customer1.domain.com? Or would they be customer1.app.domain.com?
