Stealth isn't something that I actively try to maintain, but being trans also isn't something I generally share with folks. I suspect it is this way for a lot of us that have passing privilege. There was a point early on in my transition where I actively wanted to move away and essentially start a new life once my transition was over. But now that I'm nearing the end of my transition, I'm feeling like it's not necessary.
The people who have always been in my life don't misgender me anymore. I can't remember the last time someone used the wrong name or pronouns with me. The only time any part of my transition has been discussed usually ends up being when other people in my life are having some kind of surgery and they want advice (I've had a bunch of female friends from high school message me very respectfully asking how top surgery was, because they were each getting breast reductions and were worried). New people, as far as I can surmise, have no idea that I've transitioned.
So, in my experience, it wouldn't be necessary for me to move away or stop talking to people or lead a double life in order to achieve the degree of stealth that I'm comfortable with. That has all come about organically with time. It did feel very necessary in the beginning. Now, not at all. If I end up moving, it'll be because of greater economic opportunities or a reduced cost of living - wouldn't be anything to do with my medical history.
The only thing I did do that was out of a desire to be more discreet was pruning my Facebook page. I didn't want to start a new one. I deleted a bunch of people that I never really talked to, removed pictures that I wasn't happy with, untagged myself from things, etc.
