I am in no way qualified on this, but my assumption was that this comes from cultures that consider getting straight to business rude.

So while I do find it annoying, I also try to be polite back and I certainly won't be putting some "No Hello" link.

If it is a cultural thing and coming from a place of politeness, then I'll engage in a quick round of pleasantries. Once people are familiar, I've noticed this stops.

That’s not going to make the front page of HN though.

Sure, if you’re the 0.00001% that need that. It’s going to be over engineering for most cases. There are so many simpler and easier to support things that can be done before trying this sort of thing.

Following the example, why is all the data in one giant request? Is the DB query efficient? Is the DB sized correctly? How about some caching? All boring, but if rather support and train someone on boring stuff.

Not when "off the shelf" is the motto. They'd still have to outsource the development and at that point would be questioned why spending that much money when Telemessage sells the product.

Unfortunately, the financial structure doesn't really make it easy for custom DoD software.

"Spring Boot Actuator. “Up until version 1.5 (released in 2017), the /heapdump endpoint was configured as publicly exposed and accessible without authentication by default."
