Would it be useful if somebody wrote local-pull.c similar to
http-pull.c, which clones one local SHA_FILE_DIRECTORY to
another, with an option to (1) try hardlink and if it fails
fail; (2) try hardlink and if it fails try symlink and if it
fails fail; (3) try hardlink and if it fails try copy and if it
fails fail?

Then from a source repository that contains good stuff plus
throwaway experimental commits you can prepare pruned for-public
tree.  Of course you can do it today by copying and then running
git-prune in the destination, though.
