I don't care if Tracer is lesbian or straight...but the lesbians and trannies sure do.

Its only ever really relevant in RPGs to begin with. The only genre where the character's outside life ever comes into play as an important piece of information.

But where it does become relevant for other genres is for porn, of which Overwatch is famous for, something trannies and Leftists consume gluttonously. Its why they treat shipping drama as life or death, because it might ruin their 2tb of porn by making it "non-canon" (another concept they obsess over).
