If it's someone else's project, they have full authority to decide what is and isn't an issue. With large enough projects, you're going to have enough bad actors, people who don't read error messages, and just downright crazy people. Throw in people using AI for dubious purposes like CVE inflation, and it's even worse.
Especially with the new features added last year (parent tickets, better boolean search etc) although I'm not sure if you need to opt in to get those.
In fact, it's become our primary issue tracker at work.
