Kernel mode anticheat software is something of a divisive topic. Many players believe it negatively impacts their games' performance and could potentially compromise their system's security; but many players also want something done about all the unscrupulous players, and broadly speaking, kernel-level anticheat is the most effective way to keep things clean. It is, as they say, a conundrum.
A new addition to Steam won't change any of the above, but it will at least make it easier for people to know what's going on and react accordingly: A field on Steam store pages will now enable developers to clearly indicate what sort of anticheat software their games are using, and in the case of kernel mode anticheat, will require that disclosure.
