existing contenteditable spec

Hey,
I was recently asked whether we are also editing this spec:
https://dvcs.w3.org/hg/editing/raw-file/tip/editing.html

This seems to be something creating under the WhatWG in around 2012 or so.
It does contain some basic ideas on how execCommand some and some other
essential contenteditable elements behave.

I would suggest that we will take over this specification unless someone
else is editing it and add anything related to execCommand and other
contenteditable parts mentioned there.

Currently our specs build on the concept that execCommand is being spec'ed
somewhere else, so if such a specification already (partially) exists in a
W3C spec, then we should build on that spec or replace it, or drop
execCommand entirely.

Anyone here who would like to edit this spec?
