I think part of the problem here is framed by the desire to consistently frame the matter as one that's relevant to activists and not to the rest of the world.

I read a forum comment between two writers who were both trans and who both wanted advice on how to write good characters. From what I could gather, they wanted their characters to be a mouthpiece for general trans-activist positions. Their plays would've become agitprop and likely rubbish - though possibly lauded in some very progressive circles. Theatre like this preaches to the converted.

I have zero problem with a trans actor playing any of my characters - better still I have no problem with people adjusting my characters to be trans and not making a point when they do so. They're written to be full rounded human beings and as such I don't mind if they're interpreted as trans - there's no evidence to suggest they are or they aren't in most of my scripts - just a heteronormative and cis presumption. People can do with my scripts as they please, not as performative inclusive edginess but as a normalising experience for everyone involved. Not an artistic statement, an absence of statement.

I often think we're putting all our energy in the wrong place. Lots of effort, energy and harrumphing to move us backwards at every turn. Lovely to see your name pop up as always :o)
