On my mirror of linux.git forkgroup with 780 islands, this saves nearly 4G of heap memory in pack-objects. This savings only benefits delta island users of pack bitmaps, as the process would otherwise be exiting anyways. However, there's probably not many delta island users, but the majority of delta island users would also be pack bitmaps users.
