I’m sympathetic to that point of view. But I think that in any setup I can currently imagine we are going to have working groups (from the board through to a highly focused limited timeframe group) that will want to meet together, record their thoughts, decisions, proposals, and share that thinking with others. The kind of workflow I describe above (or some variant thereof) is going to be necessary for any such group. So I don’t think it would be effort wasted or duplicated.
You raise a separate question, namely the future of the current Haskell Foundation Working Group. My personal view is that it, or something like it, may well be useful into the future. We want a “way in” whereby people who would like to contribute to the Foundation can actively do so.
You might say that anyone can, but my experience is that when everyone is responsible then no one is responsible. Example: I pay a lot more attention to GHC proposals because I am a named member of the group that has (as volunteers) agreed to pay careful attention to GHC proposals and ultimately decide about them. I would pay much less attention if I had not explicitly made that commitment, and was not a member.
But that’s just a personal view. The long term future of the HF WG is ultimately a matter for the Board, once appointed. Meanwhile, I don’t think we need wait for that day to get good workflows in place as above – I think we will need them regardless.
