Is this just for Aura or in general? I always try to roll the edges before they dry. Am I using some outdated painting folk-wisdom?
Aura, and the other Gennex lines, Ultra Spec and Regal.
In addition to the quick drying making it impractical to keep a wet edge, the way the new waterborne colorants in cross link with the resins makes it unnecessary.
When the paint companies realized their colorant systems were not going to comply with increasingly strict VOC regulations many of them modified the traditional colorants (glycol based) to comply. Rather than do that, Benjamin Moore developed a totally new water based colorant system which in addition to being 0 VOC, has increased performance qualities.
Gennex paints really do represent an improvement in coatings technology.
