Based on T95702 solution to implement citations without references (after bullets), the ability to implement harv style citations can be a lot straight forward.
We add an additional tab to "Automatic", "Manual" and "Re-use", named "Harv", on "Cite" button.
Selecting "Harv" fetches the list of bulleted citations to select from (+ ability to combine more bulleted citations and add comments if needed) in order to create a harv reference.
Needs / reasons for VE implementation of harv citations:
- Many experienced editors make mistakes with harv citations by code
- Unused buletted harv orphans are left behind after manual ref deletions or alterations
- Bots are needed to make sure the harv citation code is clean
- Avoidance of article "owners" who find excuses for reverting non-harv style cited content
