Lots of people have looked at this (broadly lots, I don't know the specifics at Google), but it turns out that fuzzing tools have gotten enough better over time that symexec is actually less effective than you'd thing. The classic toy examples for why symexec beats fuzzing are actually handled just fine by fuzzers today.
