No, SHOULD is defined in the RFC, not by colloquial usage. Google is on the wrong, regardless of their "safety" intent.
After all, linguistics is full with examples of words that are spelled the same, but have different meaning in different cultures. I'm glad the RFC spelled it out it for everyone.
