Displaying the contents of <output> is the fallback behaviour we want.

New <button> types will fallback to submit buttons (in conformant UAs) 
which is what we want, since it allows authors to implement the behaviour 
on the server side, as in this demo:

Not sure what you are referring to here, these aren't new in HTML5.

With <menu> you can chose if you want the fallback behaviour to be "show 
something" or "show nothing", since both use cases make sense.

Not if that element wouldn't do anything useful anyway. For example, you 
wouldn't want a context menu to degrade to something visible, you would 
just not have the context menu feature.

No, I had understood that. I don't see how my reaction was wrong. The 
problem with the above is that you want to hide the <menu> while it isn't 
shown. If the <menutitle> is a child, then it will be hidden too.
