Example: if there's a series changing calling conventions for some method
brewing in vfs.git and changes to filesystem's instance of that method
in the filesystem tree.  Then I'd rather it coordinated before either
gets merged.  It might be an invariant branch in either tree pulled by
both, it might be a straight pull into vfs.git and sorting the things out
there - depends upon the situation.
