Entra ID Allows People to Update their User Principal Names
Entra ID allows unprivileged users to update the user principal name for their accounts via the admin center or PowerShell. It seems silly because no justification for allowing people to update such a fundamental property is evident. Perhaps Microsoft has some excellent logic for allowing such updates to occur, but blocking access seems like the right thing to do.

Yes, exactly. And don't get me started on how that "change" affects business applications like, oh, I don't know, D365! In which the new 'name' or 'new ID' does not get updated (even though it's a Microsoft product. And guess what, you can't update a name or ID in D365. You must disable the old user and re-import the edited Entra user to make them sync. Because the old user (old name) still shares the telemetry ID / Object ID with Entra.
