 I don't follow how these two issues arise, if the server will do the
pruning for you. It will just skip entering some tree objects when doing
object traversal; why opening the git protocol or faking commits? This
would be a simple extra capability in the protocol.

Wouldn't that be as simple as passing a pathspec to git-rev-list? Not
a lot of overhead there I reckon.

One question is what to do with delta chains including unwanted
objects, but I think that given the objects' associativity for delta
chains, this shouldn't be huge practical issues and it could be
affordable in principle to include even unwanted objects.

Just keep them? What we're doing here is trying to optimize in the
case that someone has a sparse checkout, nothing bad will happen if
they get too many info surely? (Save for them not getting as much
improvement as would have been possible would the pack have been
created differently.)
