The only time it matters is if the packs in repository being repacked needs to be readable by older git, which I think is only when somebody with older git uses commit walkers to download the pack into a remote repository to use. Using or not using delta-base-offset is tied to each repository, and in a sense that is similar to "repository format version".

So how about

	[core]
        	repackUseDeltaBase = true
