I think almost all Star Trek races are descended from augments. That it's just a natural evolution to gain control over the genome and perfect the species at some point. Humans had a hiccup when their first augments were defective and banished, and then they ended up on the galactic scene before they could have another go. Most cultures get multiple choices to develop an augmented society, which is generally the society that pushes towards warp development.
This is why Vulcans, Klingons, Romulans, are occasionally shown to be stronger than humans. They were perfected by ancestors millennia ago. Denobulans explicitly had an augment stage that did not erupt into a war.
Traditionally, I gather, that once they've developed the genome to their liking, they don't go all Gattaca, but instead return to standard procreative practices, just with less health risks and an easy fix should problems arise.
Vulcans (and Romulans) are suggested to be descended from a Sargonian culture that may have been a diaspora across the galaxy (and therefore the presumed source of the other Vulcanoids). It is very likely that the genetic engineering was done and forgotten about hundreds of thousands of years before anyone set foot on Vulcan.
