An API like this leaves far fewer questions of "what does it do?" than contentEditable="minimal".  What does cursor="true" do? It turns on the ability for the user or developer to place a cursor, and default movement.  It has nothing to do with dom modification.  What does commandEvents="true" do? It enables dispatching commandEvents.  No ambiguity.  However, this does make me think again about using beforeinput/input events rather than adding new CommandEvents, since those would include drag/drop and clipboard as well?

For example, Google Docs does not use native browser cursors and draws their own, so that they can show multiple cursors for collaborators and control selections entirely the way they want.  They have to use a hidden focused contentEditable region in order to get all the events they need now, but it would be a much nicer solution for them to simply enable the events.

How does that work in mobile?  iOS for example shows lollipops at the end of selections to trigger editing actions such as copy, paste, etc... if a web content was drawing its own cursor, then these UIs can't be shown for the user.  It seems to me that what they want is to use the native cursor and do every editing operation themselves.

I'm also not certain how we're going to expose an element with cursor=true but commandEvent=false or cursor=false but commandEvent=true to an assistive technology.
