The way I look at things, what suzifrommd is talking about isn't "non-binary", it's "non-cis".
If you're trans, and transitioned, no matter what you do, no matter how well you pass, you're going to be different from the people who've spent their whole lives in your new gender (i.e., cis people), in the way that immigrants will always be different from natives. Your history of growing up and living as the other gender is written on your mind and on your body.
This shouldn't be seen as all that remarkable. I grew up half a century ago, in the USA South (where, as Faulkner wrote, "The past is never dead. It's not even past.") For all that I've left the South and never want to go back, it's a part of me. I lived through the time of the Vietnam War, the Counterculture, and those experiences are a big part of my world view. If someone wants to know me, as opposed to somebody that vaguely resembles me, they need to know about that part of me.
In the same way, if I transition, and even if I pass perfectly (unlikely!), my male upbringing and my years living as, presenting as, being treated as male, and the effects thereof, will something anybody who wants to know me will have to understand.
(And if I don't transition, my rejection of masculinity and my "feminine" aspects will be things they have to understand in order to understand me.)
tl;dr -- my understanding of what suzifrommd is wanting is for the people who care about her and who she cares about to know all of who she is, not just an edited, cis-female-like version of herself. And who wouldn't want that?
(Okay, I'm sure that there are some people who don't, give me a break....)
