Situation has changed since this email: the network programming draft has now removed text related to SRH insertion.
Please comment on the text if you see text related to SRH insertion.

In general, I don't see the benefit of sending a draft which we expect would never progress to RFC. So this would not be my preferred path.
However, I guess that as always, there are exceptions and I'm not a priori aware of a process forbidding this. As of today, I'd rather not spend time on this hypothetical case.

While IESG processing is beyond my paycheck (literally ;-) ), I trust the IESG. And I don't see a reason to doubt a priori.
And even in this case, there may be a possibly to fetch back the document from the RFC editor queue.

In short: very hypothetic case and beyond my hat. As of today, I'd propose that we work on the text of the document.
