Yes. Step 3 will certainly be visible to contributors. As we get
closer to being able to switch over, we'll probably want to discuss
the best way to approach that. One possibility is to have something
like a "./configure" script, as is common in many open-source

I don't fully understand the constraints of Apple's central build
system. It might be worthwhile talking over the constraints with
someone who's an expert.
If the requirements are that the entry point to the build system is an
xcodeproj, we can create an xcodeproj with an action that creates the
other xcodeproj files and then defers to the generated projects as
dependencies. I haven't tested this approach, but I suspect we'll
find something that satisfies the Apple-internal constraints.
