I don't think I want to do that. A lot of the functionality people use outside of repositories, such as index-pack and ls-remote, actually operates on repository objects and so it makes sense to use the default. For instance, it will be a major inconvenience to still have to specify a custom object format three to five years after the switchover. -- brian m. carlson (they/them) Toronto, Ontario, CA
