Which, thanks to Orchis, is no longer the case. Tony found out earlier in Duggan's run by hacking into one of Feilong's Stark Sentinels that the Fantastic Four, the Avengers, and other nonmutant heroes were also on Orchis's list of targets for elimination. Hell, Uncanny Spider-Man #4 had a Stark Sentinel give a (presumably deliberate) false signal implicating the original Spider-Man as a mutant to turn the public against him when he spoke out against an impending lynch mob for a regular pizza delivery driver who was leaving something as a tribute for the X-Men's Treehouse.
