We are also seeing this change in production.
What provision has been made for Powershell cmdlet output and GUI updates for this change? For example, the get-mailboxfolderpermission cmdlet now lists the Identity as the GUID (guid changed in example) with no other properties to ID the user (see below).
Also in the GUI the 'Manage Email Forwarding' screen just lists the GUID.
A blog is not a good enough forum to notify about such a large change that breaks so much existing functionally.
