Nope, I don't think so.

The only actual filesystem _breakage_ has been the introduction of pack-files (and the old, old _old_ thing where I changed the actual object compression/hashing order).

The "objects/info/alternates" thing is an extension, which allows you to have a partial object store, and point to the "rest of it", and still have all the tools understand it and be able to parse the totality of it. So it doesn't break or change old formats, it only allows a new one.

(Partial repos have always worked with the rsync protocol, and with the client-side pulling. But that was more of an accident than anything else, and they fundamentally were broken for any real work - gitweb can't show anything really sane, server-side serving - whether anonymous or ssh - doesn't work, etc etc).
