Should have thought on that. Anyway, checked out TYPO3_4-7-2 and made git submodule update --init "Could not read from remote repository" I get this error for the very first submodule. When doing git submodule deinit typo3/sysext/dbal I get it for the next in line (extbase) Is there a functional difference between 4-7-2 and 4-7-17?
