   If we are talking about git submodules, there is the user option 
   project-vc-merge-submodules.

We are talking about seperate, sometimes different, revision control
systems, or even entierly different locations.

   Otherwise, it depends on how the sub-projects are structured. Which 
   project backend is responsible for them, for instance.

What is that? I could not find any documentation what so ever on
project.el.
