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.

It seems to me that what they want is to use the native cursor and do every editing operation themselves.

Your point is still valid, but I think the selection API would need to be significantly extended in order for them to make use of it, rather than doing their own thing.  In particular, they want to be able to draw multiple cursors (the primary user selection and those of collaborators)

I don't think cursors for collaborators need to be drawn by the UA since users won't be interacting with those directly.

Could you elaborate on what kind of granularity they need?

While we may not immediately satisfy all of their needs, we should still take their use cases into our consideration so that new API will be forward compatible with their use cases if any.
