Remi:
I think we can agree to disagree. But I will continue to approach this from an amateur historian's point of view, which I feel is at the very least equally as valid (even if it pays less). And whether my opinion is supported by a minority of "established genealogists" really doesn't matter that much to me, as I feel I am in the majority of your potential consumers. If you want an expansion of the market you are aiming to sell your services to, you need to look at giving people what they are after, namely the people in our family tree as they are known in history.
As to your "school of genealogy," this is a do-it-yourself tree, not a genealogical "Hogwarts". In case you hadn't noticed, pretty much everyone here is interested in how their family is situated in history, not genealogical standards (or if there is an interest, it is far from an overriding one). They may have a passing interest in how the birth name was, primarily as it appears on the birth certificate. But they are also interested in the marriage certificate and the death certificate, and yes, how the name appears on the tombstone. Or how they are recorded on their children's birth certificate.
This is the full package that we consumers are after. Don't believe me? Look at the tree. The majority of the names out there, where there is a difference between birth name and known name, are not using the birth name. It may be referenced in events early in life, but for the most part that's the limit.
But I admit that you do well at being persistent. I admire that. And yes, I agree to disagree. Perhaps someday, as more DIY options come up in this field making it further difficult to sell an incomplete product, it will be you who changes your position. If that turns out to be the case, I'll promise to respect and admire that as well.
