There are a bunch of use cases which people see as subprojects, with 
slightly different desires. For example, I personally don't think there's 
any point to subprojects if a commit of the parent project doesn't specify 
the embedded commits of each subproject (so, for example, you can use 
bisect on the parent project to figure out which act of updating a 
subproject broke the resulting system). AFAICT, your design doesn't handle 
that, but uses the most recently fetched versions of all subprojects, with 
the revision control of the parent only handling revisions in the 
arrangement and membership of subprojects in the parent.
