Personally, I think that it should be less like “don’t use different pronouns if you’re cisgender” and more like “if you click more with different pronouns, you should look into how cisgender you are”.
She pronouns feeling more and more strange as time passed by in my life was one of the things that made me question my gender, when it registered in my mind I didn’t have to be cis… turns out I’m not cis.
