I'd rather have a comprehensive list, including everything, than a conservative one that's restricted to just things with a lot of effort lined up. It's easy to add information showing how far along a client is, checkboxes for different sorts of functionality, and that can give an idea of how much movement there is on a given client, but I think that it's hard to keep track of all the current efforts right now. Having a comprehensive list makes it easier to find what's out there.
