Would love to see an example of a booking employee (current or former) claiming they're false. I looked into a number of them first hand and they weren't (last I did that would've been 2016/2017 and certainly didn't audit the entire code base).
Sorry for the self reply, some context. The reason I looked at a number of these urgency messaging implementations is that we'd gotten a bunch of allegations from legislators that they were wrong. I was in a senior enough position that I would've been able to push back on anything dodgy/outright lying I would've found. I didn't find any that were incorrect.
