Retroactively adding a filter can be useful for existing shallow clones as they allow users to see earlier change histories without downloading all git objects in a regular --unshallow fetch. Without this patch, users can make a clone partial by editing the repository configuration to convert the remote into a promisor, like: git config core.repositoryFormatVersion 1 git config extensions.partialClone origin git fetch --unshallow --filter=blob:none origin Since the hard part of making this work is already in place and such edits can be error-prone, teach Git to perform the required configuration change automatically instead. Note that this change does not modify the existing git behavior which recognizes setting extensions.partialClone without changing repositoryFormatVersion.
