From my understanding, the impetus was that F5 submitted a CVE for a vulnerability, for an optional, “beta” feature that can be enabled. Dounin did not think a CVE should be submitted, since he did not considered it to be “production” feature.
That said, the vulnerability is in shipping code, regardless of whether it is optional or not, so per industry coding practices, it should either be patched or removed entirely in order to resolve the issue.
The messaging around this so far doesn't lead me to want to follow the fork on production. As a sysadmin I'm not rushing out to swap my reverse proxy.
The problem is I'm speculating but it seems like the developer was only continuing to develop under condition that they continued control over the nginx decision making.
So currently it looks like from a user of nginx, the cve registration is protecting me with open communication. From a security aspect, a security researcher probably needs that cve to count as a bug bounty.
From the developers perspective, f5 broke the pact of decision control being with the developer. But for me, I would rather it be registered and I'm informed even if I know my configuration doesn't use it.
Again, assuming a lot here. But I agree with f5. That feature even beta could be in a dev or test environment. That's enough reason to know.
Edit:Long term, I don't know where I'll land. Personally I'd rather be with the developer, except I need to trust that the solution is open not in source, but in communication. It's a weird situation.
Frivolous CVEs aren't a good thing for security. This bug was a possible DOS (not e.g. a privilege escalation) in a disabled-by-default experimental feature. It wasn't a security issue and should have been fixed with a patch instead of raising a false alarm and damaging trust.
