No, this is what should never happen. I wrote fuel estimation software for cargo 747's and the one thing I would have never ever wanted to read is that an airliner of the company I worked for had landed with too little fuel.

Right but this is an emergency… they didn’t plan to run out of fuel

Clearly, that's why it makes the news.

Are there ever situations where running into the reserve would be a good trade off?

This one. The reserve is there in the same way that a crash barrier is there on the highway. You really don't ever want to use it, but when you do use it and it ends well you treat it just as seriously as though you would treat a crash.
