Packfiles are nothing but a compression/storage scheme - which is a couple of levels under git-objects conceptually. Saying that "git stores content in deltas because it uses packfiles" is like saying "git stores content in deltas because it uses compression". Of course it does. You'd be hard-pressed to find any tool similar in functionality that doesn't compress content before persisting it or sending it over the network.

The Linus' original insight that made git successful in part was exactly the fact that: You don't need to do the delta scheme on the VCS-object level, but you can just use it on the storage/compression level. So conceptually CRDTs are more similar to the VCSes of the past (e.g. SVN) than they are to git.
