Just using my legal name, I didn't get any hits on the first three pages, and then I stopped looking... there were a lot of obits, actually. So many other people share my name. Or used to. No photos show up, either -- I'm so glad I've never posted photos of myself online. Looking up someone I transitioned with back in the day -- got one photo, and no mention of her past, just one of her current interests. Others friends, I get only their recent business references on google, and one who used to post regularly back in the day under a pseudonym, well, even that pseudonym is pretty much dead in the search engine now.
Importantly, perhaps, none of us maintained any professional links (or much of any kind of link, really) to our pasts; we all moved on to new careers.
So I still think it's possible to effectively maintain a closed narrative and practice non-disclosure (really, it's not "stealth" and I don't think it helps to refer to it that way, despite that common shorthand). It kind of depends on how you live your life, and what you're willing (or not) to give up. While it's always possible for narratives to inadvertently be opened, I'd still be inclined to call this "bad luck" and not really a refutation of practicing non-disclosure, any more than the possibility (and widespread prevalence) of an automobile accident is going to get me to stop driving my car.
