As someone with genetic medical conditions in my family I don't think the significance of a DCs genetic history should be ignored to spare the feelings of adoptive parents.
I'm sorry but I can't get past this statement.
Thats so fucking offensive to adoptive parents. That we are such wilting flowers and the system is geared towards sparing the feeling of the adoptive parents 
Yeah thats our aim - sod what our children need to know to make sense of their life, as long as we are protected. Most of us even pretend to have given birth to our (adoptive) children and keep them in the dark all their lives so we feel better. And we hide all that oodles of information about medical and genetic history that we get about our children so we can feel better
.
No fucking idea, OP. None at all.
FWIW the surrogate mother will always be treated as the legal mother at birth, gay couples who conceived their child using surrogacy will have gone to court to get a parental order to put both men on the birth certificate. Surrogate mothers have to consent to this. I suspect that the original birth certificate will always exist, I also highly doubt the form actually describes David Furnish as "mother"
Are you worried that DF's boys might think he actually gave birth to them?
The time to object to this was in 2008 when the law was changed.
