You make a good point. The OP is entitled to ask “Why doesn’t it work like this?” Not to have to justify if it’s needed. I understand that everyone uses different methods to create. Like you, I think a less dramatic approach might get a better result. But if a render with phase reversed is null - isn’t this a case of some users not being satisfied with the result? I think using numbers as a benchmark is flawed in this case. I’ve yet to hear VA produce clangers.
