Except the thread and concept isn't about sexuality, it's about queer sexuality. How is a lack of sexuality a queer sexuality was the question? If it was about sexuality you'd have a bigger issue of why you left out all heteronormative sexuality, which is generally considered the majority.
And, no, we wouldn't, because calling it transitioning would be rather foolish in the light of its meaning to the trans community part of the greater queer community.
