Trying to respond to a signal is a nightmare of routing and lifecycle bugs. Never mind the fact that most dependencies won't be registered. Currently file/process signature matching is ok for major runtimes, and tends to fail on specific version detection. This would effectively formalise that.
I could see it being a successful standardisation for major runtimes and many libraries that wouldn't currently be detected - but take up would never be universal. A kind of CVE search stamp.
