Blows my mind how countries make such a big deal out of changing stuff like names and markers. All it took for me to change my id documents when I transitioned was a 10 dollar fee and 2 papers to change my name legally, and a 20 dollar fee and 10 papers with 2 signed and stamped by my MD and Psychiatrist to change my birth certificate which was done prior to surgery.
It's easy to do in most of Canada and society hasn't had any issues or fell apart because of it. Even the most conservative of places allow it to be done easily here in Canada, hell my conservative as fuck province even paid for my GRS in full.
