I don't think queues like this are a panacea but they are a good idea. They buy time. That's the whole point. Time to respond. Time for a paper trail. Time to investigate. Time to cancel.
Have a normal path, eg days, a week or more (a month!). Have a selection of fast paths. Much shorter time. Days or even hours. Exceptions require higher trust. Indicators like money / reputation / history could be useful signals even if its only part of a paper trail. Treat exceptions as acceptable but requiring good reasons and explanation. This means a CVE fix from someone with high reputation could go through faster. While exceptions don't reduce the need for scrutiny they do enable clarity about the alternative chosen. Mainly because someone had to justify it away from the normal path. That's valuable in itself.
There's no perfection here. Credit cards and credentials get stolen. Reputation drifts since people change for all kinds of reasons.
Queues buy time. Time to find out. Time to back out.
