This obviously creates many problems including that two people using different citation systems cannot share org files.
What is the general view of the community about this? Is there a comprehensive discussion of pros and cons of each?
What is everyone doing? I was an org-ref user for long before I switched to org-cite. I can now shift to citar but since I am an ivy user, the switch is not trivial. Also, I like many helper functions that John has created, and would have to miss those if I do not use org-ref/org-ref-cite.
This seems messy.
