Thanks, Jack. Here I'm solely focused on making DIP1002 stronger so I've 
sent a number of suggestions that I believe would improve the proposal. 
Although you are free to argue here that in fact the proposal already is 
strong enough, this is not a "minimal requirements" setup in which a DIP 
is good to go as long as it passes a checklist. The demand here is 
elastic; the stronger the DIP, the better. Once submitted, if rejected, 
the only way to propose a similar feature is by authoring a new proposal 
with a completely novel perspective. So official review is an important 
milestone with a high bar. -- Andrei
