[[Special:PasswordReset]] seems to be a new page and is currently forcing login on at least otrs-wiki, internal, collab, and office.
Needs whitelisting in many places (there are more I didn't try yet) but I'm not certain this should be done across the board. (I also have no complaints if it is done globally) OTOH, I don't want to wait for each wiki to make it's own decision. I'll let someone else decide the criteria. :)
