Right it doesn't. But your ryppl code doesn't handle that either since
it fetches the repos individually from the non-version-specific master
branches (AFAICT). And the sublime code uses its own metadata files,
".sublime-package" and "package-metadata.json", to determine what to
get. Although I can't tell if that contains specific version info. But
since it also looks like it works with clone repos perhaps it doesn't
need to worry about that.

Perhaps, if one happens to have an not reliable internet connection. But
I would expect testers to have reliable connections. But that's a minor
unreliability.. The more likely problem is in code bugs in the testing
