I think everyone who peruses the forums would know that with systemd "halt" just halts your computer.  Slightly Abrasive +1
This seems a bit harsh. I interpreted that post as a "Here's a solution. I haven't looked into why this works and the other way doesn't so I can't give you an explanation. But my solution may work for you to." That's not asking somebody else to do your research for you. It is just explaining that you have no interest in a particular line of research. Otherwise, anybody who knows a solution but cannot explain why it works will have to refrain from sharing that information or at least prove that they have researched an explanation with no success. Since there are likely lots of cases in which people care enough to find a solution but not enough to chase down why it works, I think that would make the forums less helpful than they might otherwise be. It's one thing to try to get other people to build your house for you because you can't be bothered. It is quite another to limit your efforts to making a tent because you prefer camping.
