Splitting this off from the parent task, as there was consensus there for this and we should do changes in smaller steps where possible.
As a user and sysop on Wikinews I am protesting against this change as in most if not all that language versions the term "publish" (or its equivalents in other languages) is used for the one special edit when an article is considered ready, well after it was proofread, doublechecked and reviewed, when it usually get halfprotected and is added to the main page and declared to never again modified anymore. The change would add confusion to the redaction processes in Wikinews.
As a side note: i am not sure about wether the change would not put editors on risk. Some jurisdictation could begin to hold "editors" as "publishers" in the sense of presse laws when the button is named "publish".
