Ira Stephen Behr and Ronald D. Moore later lamented that they didn’t push back harder against Berman and other producers for queer representation on DS9 in the DS9 documentary What We Left Behind. They notably had tried in the beginning with Garak and Bashir and were immediately shut down.
Behr, in particular, really felt bad about it.
Edit: Andy Robinson, who played Garak, had a real “fuck you” attitude about that and continued to play Garak as “omnisexual” anyway. There are little hints and innuendos throughout the entire entire series between him and Dr. Bashir.
