This issue here is the biological truth of the matter.
It won't matter if the child grows up and marries the biological child of one of their adopted dads or even if the surrogate mum but it will matter if they marry the child of the woman who donated eggs.
I think more and more that there should be a separate document to a birth certificate which, where known, records the biological truth for health reasons and posterity.
The children will no doubt be greatly loved in whatever family they grow up in but who they procreate with, what inherited conditions they might have and their ancestors are dependent on their biology.
The second document will serve for subsequent additions the parents or they themselves wish to make in the future.
