The entire conflict here is that norms about what's considered responsible were developed in a different context, where vulnerability reports were generated at a much lower rate and dedicated CVE-searching teams were much less common. FFmpeg says this was "AI generated bug reports on an obscure 1990s hobby codec"; if that's accurate (I have no reason to doubt it, just no time to go check), I tend to agree that it doesn't make sense to apply the standards that were developed for vulnerabilities like "malicious PNG file crashes the computer when loaded".
