What will be interesting is there's a lot of recent work to suggest IQ/personality differences can be seen through physiognomy, and it'll be interesting to see if as this tech gets better, the people who go through this process start having similar looking children.
While a lot of physical characteristics are indicative of some sort of underlying health defect and those defects can have effects on IQ/personality and humans are very evolved to detect these things, that doesn't mean that the absence of these defects through genetic modification will necessarily lead to similar looking people.
For an example of this take a look at the picture of The Martians[0], a group of individuals considered to be astoundingly intelligent. Despite coming from the same time and place and small ethnic group they bear a passing resemblance and many of them look quite different.
Now this doesn't get into the possibility that humans will use genetic modification to impart superficial aesthetic choices on their children that will be subject to the fleeting whims of fashion as we're already seeing with cosmetic surgery and injectable fillers/botox that kind of stuff will be subject to the cyclical nature of fashion/style and not intrinsic to the any sort of physiognomy.
If anything we're likely to see people who look radically different than any traditional expectations of beauty and the traditional correlations between appearance and intelligence will be totally out the window. Sooner or later we'll be able to create people who have feathers instead of hair and someone (probably the kind of person who currently has gauge earrings, split tongues, and eyeball tattoos) will decide that this is what they want for their kids.
There isn't going to be clean mapping between intelligence and someone who has feathers for hair, or purple eyes, or three breasts.
What work are you referring to?

I'm not saying it's very exact, but I think the general premise holds true: there will be certain options we can choose from, and those options will lead to a certain convergence of traits or features. How strong the convergence will be is yet to be seen (if it happens at all)
