still using `git pack-redundant` - alternatives?

Hi,

I have some scripts for personal automation where I use git for backups and file synchronisation between systems.

It uses some form of tiering where large files, older files, and files no longer present in branch heads, move to slower networked storage and get linked via the "alternates" mechanism.

Since repacks are too expensive most of the time, I use `git pack-redundant --all --alt-odb` to clear out "local" packs which contents have become available in an alternate.

So since pack-redundant is nominated for removal, I would like to know if there are any alternatives for this type of book-keeping. Of course I can use `git show-index` and `comm` to implement similar functionality, but using built-in facilities is less error-prone and more efficient most of the time.

Cheers, Mathijs
