I think what is more likely to happen here is just a continuation of the natural ebb and flow of code-makers and codebreakers. For thousands of years, some groups of humans have been trying to find ways to protect their communications, and other groups of humans have sought ways to break those protections. At times the code-makers become aware of the breakthroughs that the codebreakers have made and change their tactics, or new technology gives them a new cipher. Either way, the codebreaker sets a setback and has to change their tactics as well. This new revelation doesn't seem like anything too different from that cycle - it is just revealing a larger breakthrough than is regularly revealed.
