If Janeway and Sisko spoke, and there's no reason to think they didn't, why would the Dominion come up? Janeway was on a search-and-rescue mission for Tuvok, with capturing Chakotay et al. a secondary concern. The relevant intelligence debriefing would be on known Maquis activity and bases in the Badlands. When and why would the Dominion be a topic necessary to discuss?
