Once we have greater mastery over genetics it will be possible for a trans person to change their gender *perfectly* rather than the imperfect methods of today, then there will be no difference between the human convention and the biological fact.
The unspoken assumption here is that social interaction must be dictated by biology, specifically chromosomes here.
Society and social interaction are the mechanisms by which discrimination act, not through some determinism based on genetic material.
Further, interestingly, positive social treatment or affirmation of trans people's self-determined identity is a huge factor in general for a trans person's happiness - not necessarily bodily changes.
That is to say, transphobia is a massive source of stress (and death) for trans people, and for a significant number of trans people, its not the body that is the source of stress, but rather a tool to help alleviate the stress (given that if one's body "passes" for a cis person's, they are less likely to be the target of transphobia).
(That is not to say that there aren't also plenty of trans people whose gender dysphoria will disappear with social affirmation. There are indeed many trans people for which gender dysphoria is strongly linked to the body and no amount of social affirmation alone will totally treat that.)
At its base, even with a significant advance in medicine, there is no way to say that genetic manipulation will actually help since social interaction makes up a significant source of stress.
EDIT: What I mean to say is that the "biological facts" you talk about is far faaar separated from social interaction and that using it as an excuse as so many do to treat someone as they would not like to be treated and cause harm (i.e. transphbia) is bad.
Like, it's not important to know someone's genetic makeup to have decent, positive social interaction with them and knowing someone's genetic makeup is not necessary nor sufficient to be a shitlord to that person.
