It hasn't gone away. I'm a cis male, pansexual, married to a Trans enby who's also pan. We're poly with relationships outside of our own marriage.
I assure you that LG vs BT still exists. I've had people accuse me of not being honest with my partner (They know both my gfs, and I know both their gf and bf), or that I'm not actually pan because I'm only with "girls" (My partner is AFAB but enby (They/Them, working on getting top surgery), and my gfs are a cis woman and a trans woman (let that part sink in)).
So because we don't fit the standard traditional relationship roles, we're somehow "doing it wrong".
