As I mentioned upthread, there are at least 2 different ways forward
(1) and (2), both of which need further work. I don't think that
additional work is impossible, but it is weeks of work, not days and
it needs to be done in collaboration with other thoughts on other
threads Corey refers to.
I have no plans on taking this patch further, but will give some help
to anyone that wishes to do that.
I suggest we Return with Feedback.
