Given the history of the NSA/CIA and so on, they probably will try to harvest all available genetic data they can to help identify people they are interested in the future. Genetic information without an identity can be matched after the fact, probably by more extensive biometric border checkpoints in the next few decades.

Plus, you could be an unmentioned adopted-out person, which would look identical, so they couldn't prove it was you without further examination.
for example, in humans it's relatively easy to predict eye colour with about 99% certainty (but only if the colour is identified as "brown", "blue", "green" - nothing complicated!), however, skin colour is harder to predict (72% correct in this paper) - https://www.sciencedirect.com/science/article/pii/S187249731...
People always assume that you can just look at the genes and immediately perfectly predict what's going on with the person in question, but a) people forget about gene/environment interaction (think about human height, only about 5% predictable using SNPs) and b) our science is simply not so far, and especially SNPs (right now the main product of 23andMe) don't predict as much as people would like them to.
To my knowledge, this has not come up yet, but I'm sure it will one day.
The CIA could not care less about your genotype.
