With respect, what's the point of discussing things that you've already
submitted upstream?... Isn't it useful to discuss things _ahead_ of
submitting them?

And I don't think this is some pie-in-the-sky 'wouldn't it be nice'
discussion. More so discussing a practical feature that is under
consideration.

I think it's actually extremely useful to get a heads up that somebody is
considering doing something, that's where a lot of value is in having a
face-to-face conversation.
