No, but as far as I can tell that’s not a requirement for the Delphi method.

Anonymity is the first “key characteristic” listed and I can’t find any mention on this page that it is optional for this method.

EDIT: Looking more into it, it seems that it went from "Delph method" to "Wideband delphi" to "Planning poker", and it's in the last step that the anonymity requirement disappeared. Very interesting!

Characteristics are not requirements. Anyway, my original claim was that it was similar not identical.
