How the state (subproject list, branch names, etc.) is recorded in a 
parent project is only important to the parent project. The parent 
project must also know how to interact with with each of its 
subprojects.

Granted, if you mix VCSes, this is most pragmatic.

But it is also wrong: The whole point in bundling the subprojects together 
is (IMHO) to get the benefits of a VCS for the root project, i.e. for the 
combined states of the subprojects. After all, you want to say "I know 
that this collection of projects at these states compiled and worked 
fine."

And if you let a build system handle the stitching of the subprojects, you 
completely lose these benefits.

Bundling and subproject support are two different things. Bundling is 
for convenience. Subprojects are usually the result of a dependency on a 
project managed or controlled by some other entity or on some part of 
the larger project with radically different development requirements.

Recording which version of a subproject to use is important and my note 
failed to discuss it. That I'll remedy over the next several days.
