More knowledge is good. Hopefully it inspires people to avoid UB and demand better diagnostics and debugging tools for UB. Avoiding UB can include such activities as completely avoiding programming in the language that has UB. UB is a post-facto justification for compiler optimizations that only work on non-buggy programs. It's a circus because programs have bugs.
