I think most implementations of a Zettelkasten _does_ include a reference system, but it is not explicitly a _part_ of the Zettelkasten, but simply a complementary tool.

I can’t comment on “long-term”, but I have been working on a paper this past week and have used my Zettelkasten notes and references extensively. Writing the draft has mostly consisted of copying snippets and titles from the ZK. Sine all my notes have references in place, the draft already have references ready to be converted to something LaTeX will handle.

I’ve also used the reverse: finding which notes reference a particular paper.
