It was, though thinking about Bel Thorne from the Vorkosigan Saga* might also be interesting.

* In Bel's case, its ancestors were created as an attempt to defeat gender norms by genetically engineering functional human hermaphrodites. It never caught on with the rest of humanity, but there's still a decent minority population of their descendents on Beta Colony. Bel didn't fit in at home so decided to go be a mercenary. Given canon technology can (and did) turn a fertile human female-assigned-at-birth into a fertile human male via growing the right organs and donation of a Y chromosome, Bel could be male or female if it wanted, and is from the easiest place in the galaxy to have that done right and without stigma.
