My personal hope - that we'll have a strong enough community development going on that we either 1) never get in the situation
2) have developers crossing the 'divide' along who's willing to dedicate some time with some fixes and being allowed to publish results with 3) infrastructure and procedures in community to make community variants / SSU's to deliver these fixes
4) a community which can make a precise request for X source to be opened, along with list of people who can actually do something about the source if it was opened and what they would do.
