I missed this before, but let me add: currently I'm more or less done
writing a preliminary specification for execCommand() and friends,
including certain aspects of contenteditable behavior
<http://aryeh.name/spec/editcommands/editcommands.html>.  It specifies
basically all the commands that browsers actually support, plus some
further things like how to handle some types of user input (text
input, Enter, Shift-Enter, Delete, Backspace).  I'm in the process of
cleaning it up and fixing some remaining details, and when I'm done
with that it should be ready for serious implementer review and
initial implementation.

This will lay the groundwork for consistent contenteditable behavior
across browsers (and consistent execCommand() behavior especially),
which should eventually remove one of the biggest impediments to
serious use of contenteditable.  As time permits, I intend to specify
more features of how contenteditable works to allow still further
interoperability.  And although I haven't attempted to add any
significant new features in the current draft, I do think it would be
pretty easy to add low-level primitives that let authors create their
own commands, as soon as I'm confident that the underlying algorithms
are all stable.

So I'm just pointing out that there's some real progress being made on
this front.  Of course, it's not good for much until implementation
starts.
