I think that these questions need to be addressed before a large and disruptive effort is undertaken piecemeal.
I've always been a supporter of boost modularization effort even though I knew it was going to be disruptive. But before investing too much effort, I would like to see us develop a more explicit overall plan and set of goals.
I've resolved to prepare a document - "the future of boost" which I hope will a basis of discussion. I realize I'm a TL;DR serial offender as I write many of my posts using the "stream of consciousness method". This time I'll prepare and review it separately before posting.
Right, I think these proposals are somewhat premature - we need to know where we're going with concrete proposals and at least prototype tools (if there are to be any) otherwise this is all just moving stuff around for the sake of it. Just my 2c.. John.
