I've known Bryony for years and she's very, very careful to trigger warn all her shows as comprehensively as possible.
She also has a therapist working on all her shows to ensure that they're "safe spaces" and if you read any interview with her, she talks constantly about the need to create safe spaces for the audience and the need to put the wellbeing of sexual abuse survivors first.
For example, here's a Twitter thread where she says that she wishes she could delete entire projects that she'd made in the past, not because of anything to do with the content, but because someone else who worked on those shows was later exposed as being a rapist.

I don't know why you're dragging my friend's name in but please stop, you're chatting rubbish about her. If you knew anything about her at all you'd know how evangelical she is about about safe spaces, trigger warnings, and she's far more hardcore than I am when it comes to censorship. She literally tweeted "it's not safe for this work to still exist" in reference to play texts with perfectly unobjectionable content purely because someone responsible for their creation was exposed as an abuser. Which I personally think is insane but that kind of attitude is the norm in theatre.
Offended everyone white, black Jews, Muslims, women and men. Scots and English didn't get off lightly either.
Still no answer as to why he was so careful to single out trans people as the one group he didn't make jokes about.
