I think you'll find that levels of acceptance and of formality can differ from one group or subculture to another. True, I have not seen "trans*" for rather a while, but simply "trans", with "transsexual" and "transgender", as well as "transitioning", used when more precision is desired. But "cis", like unpunctuated "trans", is alive and well. Maybe not in research and other formal writing, but certainly in the contexts where I see and hear this terminology. These contexts are accepting of non-binary gender and sex.

I'm a cis het male, but many of my friends, both in realspace and online, are outside the binary norm that has been taken for granted for so long. And when some members of my congregation, many of them friends of mine, formed a GLTBQ group for socializing as well as considering and studying GLTBQ-specific matters, I asked if a cis het ally might participate and got an enthusiastic "Yes". I've been very happily at many of the group's events since then.
