The gcreep was a huge wake up call for Google, back in ~2010 when this happened. I can tell you that Google took very drastic action internally as a direct result of this (my estimate is that it spent about 100 engineer years, including some very senior SWEs, in this, though that's just a guess) to make it very unlikely for this (an SRE abusing production access) to ever happen again. I'd still say that one incident in 20+ years is a huge success given the scope.
