Sorry, I didn't mean to imply that it was Google's customers specifically who should measure and be suspicious. I meant in general, say someone running a service on bare metal outside of any public cloud for example drawing this conclusion - "Google measured the impact of these bugs and mitigations and they didn't see any a significant performance regressions so I probably don't have to worry either".

Also (since you disclosed you work on GCP), I like how Google sponsored Project Zero. Fantastic work and I am sure it will be a great return on that investment. I can certainly see someone thinking about that when deciding to go with GCP vs other solution.
