Just WOW..What to say..
If your going to force a device to use two factor requirements to set up something to those users will be 'more secure' you'd also better make sure the same two-factor doesn't affect any other iCloud service either or Apple ID as a whole.
I would bet after setup u will loose access to Homepod if you then disable two factor (if u could) which only further suggests if Apple is playing "Mr. strong man" they better stand by it.
