On a more serious note, the author of this little proposal (officializing "_" as a no name placeholder) had to perform a thorough research to show that this change would not break existing code.
This kind of attention is necessary for a language with broad scope and a long successful history such as C++, and would be for every other language with such characteristics.
While more modern languages benefit from the errors of the older ones, I do not think they will be exempt from this kind of responsible growth process when they will become decades old.
Hidden gem!
