Did Kasidy Yates keep Captain Sisko's last name and their marriage after Star Trek: Deep Space Nine?

Kasidy Yates (Penny Johnson Gerald) and Benjamin Sisko (Avery Brooks) had a beautiful romance on Star Trek: Deep Space Nine. Even after she was caught smuggling cargo for the Maquis and subsequently sent to prison, it didn't change Captain Sisko's feelings for her. And when Yates returned to Deep Space Nine in season five's "Rapture," it doesn't take long for the relationship between her and Sisko to resume.

Eventually, their romance led to Sisko proposing, and Yates accepting. In the later credits after the wedding, Penny Johnson Gerald is still listed as Kasidy Yates, the scripts refer to her as Kasidy Yates-Sisko, and she is referred to as Mrs. Sisko in dialogue on the series. So it's assumed that she has taken the captain's last name.

Then, of course, the ending of Deep Space Nine happens, and Captain Sisko chooses to leave his wife and unborn child behind to stay with the Prophets. He promises to return (although that hasn't yet happened onscreen). And she is left alone with Jake, Sisko's son.

Fast forward almost twenty-five years, and, in an episode of Star Trek: Picard, according to Gamerant, there was a brief glimpse of a billboard advertising Yates' company as "Kasidy Yates Interstellar Freights." She could have simply chosen to continue to use her maiden name for her work rather than hyphenate, but this was the perfect opportunity for Picard (and Star Trek) to acknowledge that she was still Captain Sisko's wife, that she hadn't ended the marriage after being deserted for so long. Instead, it opens up the possibilty that maybe Kasidy did decide to move on. There is no way for us to clarify this unless the Star Trek franchise clears it up in a future episode of another series. One can only hope that she remained his wife and that eventually, we'll see the two of them reunite.
