Ok, got it. Yes, feel free to send in pull requests for the execCommand
spec where a lot of this will currently be described.

My personal background on some of this: I and some other JS people filed
bugs with Firefox and Chrome, some of which has to do with deletion of
content, others with caret movement, etc. . At some stage we received the
answer that these bugs would not be fixed as long as there was not a
standard to work against.  That's how we ended up getting involved here. So
I think several of us will be very interested in you guys making certain
things (such as deletion in various contexts) behave the same in all the
browsers even if we don't have a full spec. So let us know if this is now a
general policy that either Edge or all the browsers are following.
