Missing features for custom domain: catch-all address, shared mailbox, allow to share domain outside my iCloud family

Anyone knows if it is now possible to

• add catch-all address
• add a shared mailbox that goes to 2 people/all
• is the limit to only 5 members gonna change and allow me to share custom domain outside my iCloud family?

🤦‍♂️

seem like basic custom-domain email needs... am I missing something?
