I think recursing through all subprojects for most Git commands is 
actually the exception. Plus, porcelains aren't going to help much past 
the first subproject that isn't Git managed.

I fail to see a reason for this restriction. Each project should be 
managed separately. Also, how do you enforce the restriction on other VCSs?
