Why would being inside your mother for nine months, which you have no recollection of, be more important than the following years of developing an emotional bond? It's not even about making such children lack the body contact with parents since that only happens after the baby is born.
Anecdotal, but I'd have no feelings about being grown in a bag. I'd be rather happy to know my mother didn't have to suffer through 9 months of pregnancy.
I feel that strong feelings towards these things are a product of culture. Some did some good, like saying the pregnancy is a blessing to make it easier for women to pull through. But with developments like the one described in the article, these cultural norms stop being useful and can be safely dropped.
I think most people would vote for being born and having a nice childhood.
Also the bag removes the artificial limitations on brain size that is female hip.
Finally, i have seen many woman, who would love to have children, but at the same time are so bound to this sick ideal of being thin and eternally beautiful, they "train" away there children.
I think being born from a bag, is preferabl to not being born at all, any time.
