Probably not. But then, I would _not_ want this in upload-pack, so it is a strictly local thing -- either you repacked with a dictionary yourself, or there would be no explicit dictionary.

However, as I said, I _think_ this discussion is moot. You'd probably be better off making the windows wider, activating stronger compression, basically investing more time for the repacker. Plus, this would benefit cloned repos as well.
