At this point, I think we should consider installing the modules source files by default. It will still be up to the vendors whether they want to ship them. Once vendors start installing them (even if they're still experimental), this would get the ball rolling for build systems to add support for modules. It's a bit of a chicken-and-egg problem, someone needs to decide to ship something that isn't 100% ready yet. I think is has to be us.
