Junio:

Sorry for the potentially stupid follow-up question. I know that git makes a distinction when cloning locally between a direct path and a file:// URL (e.g. it's only possible to do a shallow clone from a local repository when using the file:// scheme). When that happens, doesn't that same negotiation happen locally (perhaps in a simulated way)? If that so, then theoretically the same approach could be taken with the bundle file?

(I'm not actually that interested in that feature, to be honest -- I'd much rather see further work on git-native CDN offload of packfiles, so we stop using kludges like bundle files for this purpose.)
