User Profile

I'm curious about the fact that domains need to be registered, in order to send emails to the new Apple relay service (this is if the user would like to mask their apple email address and instead provide a masked email address). The masked email address is on a domain owned by Apple, and rightfully so, they have asked that brands register domains with them to ensure they are not spammers. My question is that my client has more than 10 domains tied to one app. How does this work for them moving forward? There is little to no documentation available on this topic and I am really confused why a limit like this even exists. Could someone help?
