I think the Sisko thing was part of a fake fan script that someone had picked up and spread around the internet.
Both "Generations" and "First Contact" had fake fan script portions seeded online. Sections of "Blood and Fire" (David Gerrold's unused TNG script) had been grafted in and made it look like a gay relationship would be depicted on the silver screen. For "First Contact", the scene actually named Hawke. When publicity photos of the actor playing Hawke first turned up, many fans said, "Yeah, he's gay all right!"
