There is a difference between genomic data and biometric data: biometric data has a known potential exploit vectors. So, with a picture of your retina, a sophisticated adversary could potentially reproduce your retina to allow access to some secure facility.

Genomic data doesn't have the same risk factors--at least at the moment. I think that the point many are trying to make here is that there may be risk vectors available at some point in the future that aren't known now. A couple of theoretical examples:

* You had to give a blood sample rather than other biometric data like a retina scan.

* Spoofing DNA evidence. That would be very/prohibitively expensive/difficult at the moment, but I suppose could become as easy as 3d printing at some point in the future.
