The post had been getting super long at that point, and I also removed a bunch of other stuff that might be considered helpful. The philosophy I employed was generally only to keep direct, actionable items and remove reasons/motivation and other commentary; the main reason that e.g. you should include a MWE is fairly obvious.
For what it’s worth, I have no personal objection to adding anything back in that people think is worthwhile, but I do believe that the longer the list gets, the less of it is actually read.
