Loss of Advanced Shell in Sophos Firewall v19

From the V19 EAP 'What's New' file - "Advanced Shell – With the addition of many comprehensive logging enhancements in the GUI, and in-line with industry best-practices, access to the Advance Shell will be restricted to licensed commercial versions of the product only."

Why the distinction between licensed commercial and other licences (which I presume means Home licenses)?
