I think there are two different herd immunity versions being talked about though.
Natural herd immunity - which is what the Great Barrington Declaration suggested. This is the one that most scientists say isn't achievable without massive risk and lots of excess death. It's also never been managed by design with any other disease.
Herd immunity via ongoing vaccination - this is what is normally meant when scientists refer to herd immunity, the one we're all hoping will work, is why a vaccine is being produced, and has a proven history as it was the way Smallpox and Polio have been wiped out in countries.
