Here’s an afterthought that just hit me:
there should actually be no point in archiving the cache at all. If you had
a disaster and do a full restore from borg, the old cache data becomes
invalid anyways, because the files’ inodes will now be different. AFAIK,
inodes are one way of detecting file changes. Different inode → file must be
different → rehash.

(Unless `borg extract` updates the borg cache for files it restores, which I
doubt because the destination path is arbitrary.)
