Are UML diagrams considered in scope too?

Where did you get this info? It might be the feature is actively being worked on and the DoS is a known issue which would be fixed before merge. Lot of projects have contrib folder for random scripts and other things which wouldn't get merged before some review but users are free to run the script if they want to. Experimental compile time build flags are experimental by definition.

The whole drama seems very short-sighted from F5's perspective. Maxim was working for you for free for years and you couldn't find some middle ground? I imagine there could have been some page on the free nginx project that listed CVEs that are in the enterprise product but that are not considered CVEs for the open source project given its stated policy of not creating CVEs for experimental features, or something like that.

To nuke the main developer, cause this rift in the community, and create a fork seems like a great microcosm of the general tendency of security leads to wield uncompromising power. I get it. Security is important. But security isn't everything and these little fiefdoms that security leads build up are bureaucratic and annoying.

I hope you understand that these uncompromising policies actually reduce security in the end because 10X developers like Maxim will start to tend to avoid the security team and, in the worst case, hide stuff from their security team. I've seen this play out over and over in large corporations. In that sense, the F5 security team is no different.

But there should be a collaborative, two-way process between security and development. I'm sure security leads will say that they have that, but that's not what I find. Ultimately, if there's an escalation, executives will side with the security lead, so it is a de facto dictatorship even if security leads will tend to avoid the nuclear option. But when you take the nuclear option, as you did in this case, don't be surprised by the consequences.

It's still being tested. It's not complete. It's not released. It's not in the distribution. The amount of people that have this feature in the binary AND enabled is less than the amount of people that agree that this should be a CVE.

CVE's are not for tracking bugs in unfinished features.
