Appreciate the sentiment, but in my humble opinion, seems like they should lean into creating even better automated testing, because adding all the new bugs to their suite of automated tests would be a more certain way to decrease their chance of happening again.

But, in a sense, this still incorporates your idea, because the devs and QA must be given the mandate of finding these bugs, and also towards making the automated tests cover the bug's related test cases (as well as charged with improving the test code itself, which is often in a mediocre state in most code bases I've seen at least).
