I would think that disabling cut/copy/paste would apply to main menus 
too, not just context menus.  Most people I know who use menus for this 
(which is precious few, btw, for the most part people I know seem to use 
keyboard shortcuts for cut/copy/paste) use the main menu, not the 
context menu...

One question is whether this use case (which I agree seems worth 
addressing) requires a new event.  That is, is it better for the browser 
to fire events every time a menu is opened, or is it better for apps 
that want to maintain state like this to update some property on the 
editable area whenever their state changes and for browsers to just read 
those properties when opening a menu?

The latter is, from my point of view as a browser implementor, somewhat 
simpler to deal with, since it doesn't involve having to worry about 
alert() or sync XHR or window.close() in menu-opening code.  But I can 
see that it might be more complicated to author against...
