@gurkan About your maintenance comment: In order to not get slowed-down operations, it is necessary to remove snapshots (using forget) and to clean up and compact index files. The last one is done by prune, but prune does a lot of other things (including cleaning and compacting data aka pack files) and is hence very slow, especially with remote repositories, see also prune issues
If you do not care that much about the size of your repository, you could alternatively try
With this PR, cleanup-index followed by repack-index should do the job.
And you could also run infrequently cleanup-packs which is pretty fast without the repack-options and then deletes only completely-unused data files.
