I was looking at the history here and noticed this topic, which I
somehow missed when it happened:
$ git show -s cf0879f7e98d2213503622f780d2ab0dd3f93477
commit cf0879f7e98d2213503622f780d2ab0dd3f93477
Merge: 3710f60a80 0e37abd2e8
Author: Junio C Hamano <gitster@pobox.com>

Merge branch 'sc/pack-redundant'
Update the implementation of pack-redundant for performance in a
repository with many packfiles.
* sc/pack-redundant:
pack-redundant: consistent sort method
pack-redundant: rename pack_list.all_objects
pack-redundant: new algorithm to find min packs
pack-redundant: delete redundant code
pack-redundant: delay creation of unique_objects
t5323: test cases for git-pack-redundant
So it sounds like:
- somebody does care enough to use it
- it may not be horrifically slow anymore
So it may not be worth trying to follow through on the deprecation
(though the fact that neither of us realized this makes me worried for
the general state of maintenance of this code).
