Rick, thanks for asking me to clarify. I see your point clearly, and by assuming I am in your shoes and thus are concerned about public exposure, I'd also see no active benefit for you and your living family to become open.
However, because I've done lots of research in many and various fields, I go forward in life and genealogy and use facts as they become available. My paternal grandfather had his name hidden from history, for instance long before I was born. We know he existed because my father was born. But someone of my GF's generation decided that it was somehow "dangerous" to use his name in a publicly seen (and randomly seen) way. That decision fogs our contemporary family knowledge of our own family line through my paternal GF for our generation and all following generations, NOTHING can be known about him or his family line (which is ours as well) as a consequence of some ancestor back there being embarrassed about some supposedly delicate part of his life, known to them but not known to future generations.
As a scholar I find that decision reprehensible on the basis of the primary standards of the principles of genealogy, I hope I make my intent and that principle clear. While we cannot always avoid making mistakes, we must simultaneously and always use The Facts of the Matter.
That doesn't make us disagree. Having the test number available on Wikitree is your choice, and that seems to be important to you. I don't think anyone's going to look at my test, and I've forgotten if I posted the number or not. I want you (and probably others do too) to do what your best decision says to do. And for that, BRAVO, Rick, Bravo!
