I think what they've announced is the best fit for small businesses, not large enterprises. They can still treat it as a B2C-style service - many tiny customers with similar needs. Mom and Pop can now get a domain name through Apple, with email accounts - for a lot of people that might be the only way they'd know how to do something like that.

The business needs here aren't so different to family manangement features, say.

Throwing in Entra ID / Google Workspace authentication and multiple Apple IDs per device is probably the most "interesting" part as to where that ends up in the distant future.
