If there was no fallback would you take the performance hit (which is
huge on your repository) or do the dump/load? Both options are so
bad, that I was suggesting it might be worth the effort to possibly
support both options to give a better upgrade path.

Well, I was suggesting some kind of filesystem format that handles
lots of small files efficiently. Depending on the format, you might
not need a lot of disk space to handle it.
