I'd say there is something wrong with the process. If a trusted developer can't get somebody more privilege on the tracker by saying that "I trust this guy", then a new process is needed. That's it's too hard to get privileges in the Python development community has been evident too long, I think.
There is one privilege that should be hard to get: Permanent delete. But being able to triage bugs isn't such a privilege. Heck, not even commit access is, because of someone makes something bad, you can back out the checkin. Giving people rights to a bugtracker or versioning system is not dangerous, and should not be hard.
