Not for nothing but plenty of other companies do pretty much just this, for example in defense. Surely Google of all companies should be able to do a simple search like that on a regular basis.
In highly regulated national security impacting industries like defense, that makes sense. Google has not developed that rigor yet, although it's becoming obvious that their business has high national security implications now.
I don't think Google has ever had rigor, in anything except possible things which directly affect uptime. It seems to be a systematic problem - look at their history with chat apps for example. Great for hackers - both ones working for Google and ones working for other governments, apparently.
